In order to describe astrophysical phenomena such as glitches, X-ray bursts or oscillations in neutron stars, it is essential to understand the properties of its crust and core as well as their interface. In order to achieve this, it is crucial to develop a unified and consistent scheme to describe both the finite nuclei in the crust and homogeneous matter in the core within the same...

The talk will cover results from all LHC experiments on measurements of particle production in pPb and PbPb, multiplicity dependence of particle production, collectivity studies, elliptic flow, and jet quenching.

In this contribution, we study the inclusive and diffractive $\eta_{c}$ photoproduction in $pp$ and $pPb$ ultra-peripheral collisions (UPC's) at the LHC Run II energies. In a hadron-hadron UPC, is well known that the hadrons can act as sources of almost real photons allowing the study of photon-photon and photon-hadron interactions. Our goal is the study of the $\eta_{c}$ production in...

In heavy ion collisions after the quark-gluon plasma there is a hadronic gas phase. Using effective Lagrangians we study the interactions of charmed mesons which lead to $J/\psi$ production and absorption in this gas. We update and extend previous calculations introducing strange meson interactions and also including the interactions mediated by the recently measured exotic charmonium...

In the high energy regime, the proton structure consists of a very large number of parton that interact with each other according to the theory of strong interactions, Quantum Chromodynamics (QCD). Through QCD, the number of partons in the proton is described by equations of parton evolution that depend on kinematic variables. These equations can be linear, the DGLAP equations, and nonlinear ,...

In the present day, the theoretical description of the behavior of the cross section in the regime of high energies is still the focus of questioning. A proposal that is still valid, is that the slight growth of the cross section is associated with the exchange of an object with the quantum numbers of the vacuum, called Pomeron. Phenomenologically, via Regge's theory, it was possible to...

The behavior of charged pion masses in the presence of a static uniform magnetic field is studied in the framework of the two-flavor NJL model, using a magnetic field-independent regularization scheme. Analytical calculations are carried out employing the Ritus eigenfunction method, which allows us to properly take into account the presence of Schwinger phases in the quark...

in the description of the nucleon elastic

form factors revealed by the Jefferson Lab

polarization transfer experiments,

has been extended to the calculation

of transition form factors associated

to several light nucleon resonances $N^\ast$.

The electromagnetic structure of the $N^\ast$

In this paper we study the double quarkonium production in single and double diffractive processes considering the Resolved Pomeron model. Based on the nonrelativistic QCD (NRQCD) factorization formalism for the quarkonium production mechanism we estimate the rapidity and transverse momentum dependence of the cross section for the $J/\Psi J/\Psi$ and $\Upsilon \Upsilon$ production in...

Double parton scattering (DPS) is a mechanism in which two partons from each proton initiate a scattering process. The cross section formula is described by a partonic distribution function (PDF), a double parton distribution (DPD) and scattering cross sections relative to more fundamental hard processes, i.e., the formula can be written in such a way that is possible to describe different...

Short-lived hadronic resonance production in high energy collisions is an important observable to investigate the properties of the system created in such collisions. Measurements of particle production yields have shown a suppression in the relative production of resonances with respect to non-resonance particles for high energy collisions in which a large amount of particles were produced....

In the present work we have obtained the equation of state and the population of baryons and leptons to the highly asymmetric dense stellar matter, with the purpose of studying the effects of hyperons on the structure of neutron stars. To this end, we adopted the Zimanyi-Moszkowski model in the mean field approximation. From the equation of state obtained with the model, we solve numerically...

The following work studies the effects of the interactions originated from scalars and vectors mesons exchanges in the interior of Neutron Stars. We analyze the differences that appears on masses and radii between stars sustained against gravitational collapse exclusively by the degeneracy pressure of matter and stars that have also the presence of interactions mediated by mesons. In the...

Since long the measurement of strange and multi-strange hadron production rates has demonstrated to be a key measurement in the investigation of the properties of nuclear matter created in high energy collisions. In particular, the observation of strangeness enhancement in collisions of large systems, such as Pb-Pb, is historically considered as a signature of the formation of a QGP phase in...

The exclusive photoproduction of the heavy vector mesons J/Ψ is investigated in the context of peripheral lead-lead collisions for the energies available at the LHC, s=2.76 TeV and s=5.02 TeV. Using the light-cone color dipole formalism, the rapidity distribution was calculated in two centrality bins at 50%–70% and 70%–90% in order to evaluate its robustness in extrapolating down to a...

At forward rapidities and high energies we expect to probe non-linear effects of the Quantum Chromodynamics (QCD). One of the most promising observables to constrain the QCD dynamics at this regime is the exclusive vector meson photoproduction (EVMP). We study the EVMP in association with a leading baryon (product of the proton dissociation) in photon-hadron interactions that take place in...

Establishing a description for confinement is not something simple. In order to try to understand a little about this phenomenon, we will explore the thermodynamics of models that try to describe it in terms of propagators with violation of positivity. In this work, "confinement'' is always understood in the sense of positivity violation of the propagator of the elementary fields. For...

In this work, we investigate the exclusive production of particles in scattering processes in the so-called saturation region. Within this scheme the phenomenon of geometric scaling takes place: cross sections are functions only of a dimensionless combination of the relevant kinematic variables, which happens both in inclusive and diffractive cases, as in the production of vector mesons. In...

The photon–induced interactions, as those present in the deep inelastic scattering (DIS) process and in ultraperipheral hadronic collisions, can be used to improve our understanding of the strong interactions in the high energy regime. In particular, the photon-induced interactions where one the incident hadrons fragments and only one rapidity gap is present in the final state, usually denoted...

We study the nucleon axial (Ga) form factor in symmetric nuclear matter in a light-front approach using the in-medium inputs calculated by the quark-meson coupling model, where the quarks interact with a flavor independent contact force. We found results comparable to the ones obtained with a confining interaction.

The recent data by the TOTEM Collaboration on $\sigma_{tot}$ and $\rho$ at 13 TeV, have shown agreement with a leading Odderon contribution at the highest energies, as demonstrated in the very recent analysis by Martynov and Nicolescu (MN). In order to investigate the same dataset by means of Pomeron dominance, we introduce a general class of forward scattering amplitude, with leading...

We investigate protoneutron star matter using the state-of-the-art perturbative equation of state for cold and dense QCD in the presence of a fixed lepton fraction in which both electrons and neutrinos are included. Besides computing the modifications in the equation of state due to the presence of trapped neutrinos, we show that stable strange quark matter has a more restricted parameter space.

Study of low energy interaction kaon-hyperon throw the nonlinear chiral invariant Lagragians considering kaons, ρ mesons, σ mesons, hyperons, and corresponding resonances. We calculate the total cross section, angular distributions, polarization, and the phase shifts in the center-of-mass frame to low energy S- and P-wave.

In this work, we study in detail the effects of many-body forces on the equation of state and the structure of magnetic neutron stars.

The stellar matter is described within a relativistic mean field formalism that takes into account many-body forces by means of a non-linear meson field dependence on the nuclear interaction coupling constants. We assume that matter is at zero temperature,...

The properties of color superconducting cold dense quark matter under compact star conditions are investigated using an SU(2) Nambu Jona-Lasinio (NJL) model in which the divergences are treated using "medium separation scheme" (MSS) as regularization scheme. We compare our results with the usual treatment of the divergent integrals (3D cutoff) that is referred to as the "traditional...

The dimension two gauge invariant non-local operator A2min, obtained through the minimization of ∫d4xA2 along the gauge orbit, allows to introduce a non-local gauge invariant configuration Ahμ which can be employed to built up a class of Euclidean massive Yang-Mills models useful to investigate non-perturbative infrared effects of confining theories. A fully local setup for both A2min and Ahμ...

The Parton Distribution Function measure the probability to find a parton inside a hadron, but these functions are of non-perturbative origin and, therefore, cannot be calculated from first principles in perturbative Quantum Chromodynamics. In this work we review how the parton distribution functions are determined, specifically the HERAPDF2.0, which is determined from deep inelastic...

The search for the existence of pasta phases

in the low density regions of nuclear and neutron star matter is performed within the context of the quark-meson

coupling (QMC) model, which incorporates quark

degrees of freedom.

Fixed proton fractions are considered, as well as nuclear matter in

beta equilibrium at zero temperature. We discuss the recent

attempts to better understand the...

In this work we present a theoretical approach to deal with radiative decays of meson molecules. This is a promising framework to understand mesons that lie near the production threshold of $D$ and $B$ mesons, and don't fit in the traditional quarkonia predictions. We apply this approach specifically to the meson $X(3872)$: considering it a $D D^*$ molecule, we deal with its radiative decays...

The sigma resonance has been a long standing puzzle in both, theory and experiment. Because its non-Breit Wigner shape, the extraction of its properties is not straightforward. Dispersive analysis techniques are needed to extract the properties of the resonance. Lately, several lattice data groups have performed a calculation of phase shifts for $\pi \pi$ scattering in the Isospin = 0, Spin =...

Using the light-front kaon wave function based on a Bethe-Salpeter amplitude model for the quark-antiquark bound state, we study the Electromagnetic Form Factor (EMFF) and other observables like charge radius and decay constant of the kaon in nuclear medium within the framework of light-front field theory. The kaon model we adopt is well constrained by previous and recent studies to explain...

We present finite temperature Dirac-Hartree-Bogoliubov (FTDHB) calculations

for the tin isotope chain to study the dependence of pseudospin on

the nuclear temperature. In the FTDHB calculation, the density dependence of the

self-consistent relativistic mean fields, the pairing, and the vapor phase

that takes into account the unbound nucleon states are considered

self-consistently. The...

A comprehensive study of the heavy quark production in ultra high energy cosmic ray interactions in the atmosphere is presented considering that the primary cosmic ray can be either a photon, neutrino or a proton. We show that the contribution of heavy quarks for cosmic ray interactions is in general non-negligible and can be dominant depending of the process considered. Moreover, we present...

I will describe a holographic approach to QCD where conformal symmetry is broken explicitly in the UV by a relevant operator O. This operator maps to a five dimensional scalar field, the dilaton, with a massive term. Implementing also the IR constraint found by Gursoy, Kiritsis and Nitti, an approximate linear glueball spectrum is obtained which is consistent with lattice data. Finally, I will...

Exclusive diffractive reactions enable us to efficiently probe soft QCD dynamics in hadronic and nuclear collisions. The color dipole approach provides universal means to evaluate both the inclusive and diffractive particle production observables beyond the concept of QCD factorisation. I will overview the most recent developments in this research field, along with current theoretical and...

We study the behavior of strongly interacting matter under a strong external magnetic field in the context of chiral quark models that include nonlocal interactions. In particular, we analyze the influence of a constant magnetic field on the chiral quark condensates at zero and finite temperature, studying the deconfinement and chiral restoration critical temperatures and discussing the...

Effective interactions have been used to compute the pairing gap for nuclear and neutron matter in several schemes. Most often the BCS approach is based on having the scattering phase-shift as the basic input of the calculation. On the other hand, there is an arbitrariness in this procedure, as there are infinitely many interactions leading to the identical phase-shift. In this work we analyze...

We present results of a study of the dynamics of the formation of inhomogeneous

phases of the chiral transition transition in QCD. The possibility of the formation

of a spatially modulated chiral condensate in the final stages of a heavy-ion

collision is investigated assuming a Ginzburg-Landau-Langevin time evolution,

using model-motivated free energy functionals. Time scales for the...

The bound state Bethe-Salpeter amplitude described by a Nakanishi two-dimensional integral representation has a smooth weight function g, which carries the detailed dynamical information. The Light-front wave function can be derived and is given by a one-dimensional, integral representation with the same weight function g. By using the generalized Stieltjes transform, g can be written in terms...

We investigate the equilibrium configurations of neutron stars, quark stars and white dwarfs in a modified gravity theory, namely, $f(R,T)$ gravity, for which $R$ and $T$ stand for the Ricci scalar and trace of the energy-momentum tensor, respectively. Considering the functional form $f(R,T)=R+2\lambda T$, with $\lambda$ being a constant, we obtain the hydrostatic equilibrium equation for the...

Gravitational collapse of a star occurs when the internal pressure cannot sustain the gravitational forces. There are two essentially different mechanisms. One is the collapse due to the relativistic effects in the degenerate Fermi Gas, known in the form of Chandrasekhar mass limit, associated with the collapse of white dwarfs or core of the massive stars in advanced stage. Other is due to...

White dwarfs are compact objects that stand against gravitational collapse by their internal pressure of degenerate matter. In this work we aimed to perform an introductory study on these stars, using two equations of state: (I) an ideal Fermi gas and (II) the one by Baym Pethick and Sutherland (BPS). In addition, we analyzed these two state equations in two scenarios, the Newtonian and the...

Central exclusive production (CEP) is a singular way to measure cross section as it presents a very clean environment on detector and can be calculated (almost) exactly in many cases. LHCb is one of the four big experiments in LHC accelerator. On LHCb we have a dedicated group to work and search for exclusive processes and the main purpose is to probe and search for new insights on...

In this work corrections to the usual SU(2)-flavor Nambu-Jona-Lasinio (NJL) coupling [1] and also to the chiral pion couplings to constituent quarks [2] due to a weak external magnetic field are calculated at the one loop level. A sea quark determinant is expanded for relatively large quark mass and weak electromagnetic field and magnetic-field-dependent low energy quark effective coupling...

In this work, we investigate the thermodynamics of Walecka model, constituted of a fermionic field interacting with real scalar and vector fields, in the presence of an external magnetic field and boundaries. By making use of mean-field approximation, we analyze the phase structure of this model at effective chemical equilibrium, under change of values of the relevant parameters of the model,...

The progenitors of ultra-compact objects (UCO: neutron stars, magnetars &

black holes) must be massive stars (> 9 M_Sun). Yet none of these UCOs

has ever been found with [2 M_Sun ≤ M ≤ 5 M_Sun]. Moreover, analytical

and numerical modelling of NSs predict their central density to be much

beyond the nuclear one: untestable density-regime with unknown physics.

Based on numerical-solving...

We analyse the recent LHC data at 7 and 8 TeV for pp elastic scattering with special attention for the structure of the real part, which is shown to be crucial to describe the differential cross section in the forward region. Our description contains the zero of the real amplitude predicted by André Martin.

In the present work, we investigated the exclusive diffractive production of charmonium in pronton-nucleus collisions at the Large Hadron Collider (LHC) energies. Such exclusive production reactions possess a cleaner experimental signal than inclusive production once it is characterized by low multiplicity of particles between final produced state and the incident protons of collider beam. The...

In this contribution we investigate the inclusive double quarkonium production in $pp$ collisions at the Run 2 LHC energies. The cross sections are estimated using the Non-Relativistic QCD (NRQCD) factorization formalism, taking into account the color singlet and color octet contributions. We present predictions for the total cross sections for the $J/\Psi J/\Psi$ and $\Upsilon \Upsilon$...

In this work we discuss the two-fermions bound state problem in the extreme binding energy limit. To this end, we solve the Bethe-Salpeter equation in Minkowski space for the Yukawa model, where the interaction boson is a vector particle. We use the Nakanishi Integral Representation, which simplify the interaction Kernel of the system. Furthermore, we use the light-front projection which...

The advent of the high-energy colliders has motivated the study of the hadron structure at high energies. In such scenario, a hadron becomes a dense system and the nonlinear effects inherent to the QCD dynamics may become visible. Recent studies show that vector meson exclusive photoproduction has the potential to probe the QCD dynamics at high energies. In this work we present an analysis of...

The production of gravitons via two-photon fusion and ZZ fusion processes are considered using the scale of the gravitational interactions around a few TeV. We focus on the expected energies of the proposed electron–positron colliders with a center-of-mass energy at the TeV scale. The number of events is predicted, and the background from the Standard Model is analyzed. The dependence on the...

We explore the condensation of charged pions in the presence of a large isospin chemical potential, in the absence of baryons, within the Linear Sigma Model. A mean-field expansion is used to calculate the thermodynamics and the spectrum of excitations of the pion-condensed medium. The pion condensate is shown to explicitly break the $U(1)_{\tau_3}$ vector isospin symmetry associated with...

The study of the J/$\psi$ production in pp collisions provides important information on perturbative and non-perturbative quantum chromodynamics. The production of the heavy-quark pair can be described perturbatively while its hadronisation into quarkonium state is a non-perturbative process. These processes are not fully understood and additional experimental data are necessary to further...

The properties of magnetized color superconducting cold dense quark matter under compact star conditions are investigated using an SU(2) Nambu Jona-Lasinio (NJL)-type model in which the divergences are treated using a magnetic field independent regularization scheme in order to avoid unphysical oscillations. We study the phase diagram for several model parametrizations. The features of each...

We study the two flavor Nambu--Jona-Lasinio model within the Mean Field Approximation and RPA framework to evaluate the pole masses of the $\sigma$ and $\pi^0$ mesons in the presence of a constant magnetic field at finite temperatures.

First, we emphasize the importance of the regularization method used in this work. For this aim, we explicitly employ the Magnetic Field Independent...

The Fock-Tani formalism is a first principle method to obtain effective interactions from microscopic Hamiltonians. Originally derived for meson-meson or baryon-baryon scattering, we present the corresponding equations for meson-baryon scaterring. Then we include the gluon mass, a non-perturbative aspect, to the interaction potencial between quarks with gluon exchange. In particular, we shall...

The annihilation or production process $e^++e^-\rightarrow
\rho^+ + \rho^- $ is studied with respect to the

universal perturbative QCD (pQCD) predictions. Sub-leading contributions

are considered together with the universal leading pQCD amplitudes such that

the matrix elements of the $\rho$-meson electromagnetic current satisfy

the constraint from the light-front angular condition. The ...

We investigate some non-perturbative models for Quantum Chromodynamics (QCD) with the purpose of testing its validity in the perturbative region of nuclear interaction and to explore its behavior in the infrared region. In particular, we focus on the calculations and analysis of the potentials between supermassive quarks and antiquarks, since this observable might reveal the appearance of...

We show explicit the first radiative correction for the vertex and photon-photon 4-point function in Generalized Scalar Duffin-Kemmer-Petiau Quantum Electrodynamcis (GSDKP), utilizing the dimensional regularization method, where the gauge symmetry is manifest. As we shall see one of the consequences of the study is that the DKP algebra ensures the functioning of the WT identities in the first...

The $\mathcal{N}=1$ Super Yang-Mills theory in the presence of the local composite operator $A^2$ is analyzed in the Wess-Zumino gauge by employing the Landau gauge fixing condition. Due to the superymmetric structure of the theory, two more composite operators, $A_\mu \gamma_\mu \lambda$ and $\bar{\lambda}\lambda$, related to the susy variations of $A^2$

are also introduced. A BRST...

It is expected that the charmonium state $J/ \psi$ produced during the hadronization of the quark-gluon plasma suffers a rescattering process between the chemical freeze-out and the kinetical freeze-out. We present an updated study of the suppression and generation of the $J/\psi$ meson due to its interaction with a hadronic medium composed of light pseudo-scalar (as $\pi, K, \eta$) and...

A recently developed variational resummation technique, incorporating renormalization group properties consistently, has been shown to solve the scale dependence problem that plagues the evaluation of thermodynamical quantities, e.g., within the framework of approximations such as in the hard-thermal-loop resummed perturbation theory. This method is used in the present work to evaluate...

In this work we study the viability of the Mossbauer technique to measure neutrino-nucleus

interaction, specifically Coherent Elastic Neutrino Nucleus Scattering.

To describe the neutrino-nucleus interaction we propose a simple collective model in which the M\"ossbauer-nucleus is considered as an inert core with $A-1$ nucleons, and valence

neutron. The core is slightly deformed in the...

In this work we study the Wigner-Weyl formalism adequate for a theory with nucleons interacting through scalar and pseudoscalar fields, and for this we use the linear sigma model. Our goal is to understand the phenomena observed in experiments at laboratories such as the LHC or BNL, where a new state of matter is reached, the quark-gluon plasma. So we need to study chiral phase transitions,...

The quarkonium plus photon production in coherent hadron - hadron interactions at LHC is studied using the non-relativistic QCD (NRQCD) factorization formalism. We investigate a set of kinematic distributions and compute the total cross sections for M + γ (M = J/Ψ and ϒ) production. Our results demonstrate the feasibility of such process in the LHC kinematic regime and explore the...

The supersymmetry breaking of a supersymmetric harmonic oscillator with

polynomial interaction is analyzed. Some thermal effects are studied following TFD formalism. The restored supersymmetry results in nonvanishing energy at finite temperatures due the additivity of the thermal effects, while at $%
T=0$ the energy is zero.

In this work we calculate some exotic nuclear phase properties of the neutron-proton-electron matter known as “nuclear pasta” in the context of the Walecka model at zero temperature. We extend the usual spherical Thomas-Fermi Approximation by including non-spherical terms in the density and energy expansions in order to properly describe geometry deviations in the complex structures commonly...

The infrared behavior of the three gluon vertex is one of the most prominent subjects of study in current non perturbative QCD, playing a central role in dynamical gluon mass generation through the Schwinger mechanism and being an essential ingredient in the Bethe-Salpeter equation which governs glueballs. However, the analysis of this vertex through Schwinger-Dyson equations (SDEs) is...

In this work we show how to indroduce the magnetic field in hadronic matter in a thermodynamically consistent way. We revisit the literature and show that several common results that are derived magnetic field on hadronic matter are thermodynamically inconsistent and that affects the mass-radius results.

Utilizing the so called choatic magnetic field [1,2,3,4] we show that a...

Halo nuclei are composed by a core of strongly bound nucleons surrounded by a halo of weakly bound neutrons or protons. When scattered by a target nucleus, halo nuclei may undergo into a fragmentation process opening different possible exit channels for detection. For example, the surrounding nucleons can either by capture or emitted during the reaction. With more nucleons in the halo the...

In general, three-body decays can be described as quasi-two-body decays where intermediate resonances decay into two particles, and then observing a the final state constituted of three particles. To study these processes it is necessary to perform an amplitude analysis to the corresponding Dalitz Plot (the two-dimensional representation of the decay phase space). It is common to use the...

It is known that, at energies below the deuteron breakup, nd scattering

in the doublet channel exhibits both a virtual state and a zero in the

amplitude. We construct a halo/cluster EFT that takes both features into

account, and follow the behavior of observables as we decrease the deuteron

binding energy. Reaching the unitary limit, we demonstrate the nature of this

virtual state...

Hadronic tau decays remain an excellent laboratory for the study of many aspects of QCD. The inclusive decays have been used as a source of precise information about $\alpha_s$ for the past 20 years. In the search for higher precision, partially triggered by the LHC, several aspects of this determination have been scrutinised in the recent past. The issues that arise are often of a fundamental...

The talk will cover results from all LHC experiments (CMS, ATLAS and LHCb) on Z, photon and jet production in pPb and PbPb ion collisions, Heavy quark production Jet substructure and fragmentation, Double parton scattering.

In this work, we propose a quasi-particle equation of state with a phenomenological critical point.

The QGP phase of the model is determined by a quasi-particle model fitting to the Lattice QCD data.

At zero baryon density, the model is smoothly connected to the hadronic resonance model.

A phenomenological critical point is implemented in such a way when the baryon density increases and passes...

In this talk, I will present some the current efforts to understand the phenomenon of chiral symmetry breaking and the generation of a dynamical quark mass. To do that, we will use the framework of the Schwinger-Dyson equations. We will solve the coupled system of integral equations formed by the quark propagator and the complete non-transverse structure of the quark-gluon vertex, which is...

We review methods and results for the study of color confinement in Yang-Mills theories using numerical simulations of infrared propagators in the lattice formulation. We discuss recent progress in considering finite-volume effects, different gauges and the finite-temperature case.

The COMPASS experiment at CERN is one of the leading experiments studying the nucleon spin structure. Until 2012 the Parton Distribution Functions and the Transverse Momentum Dependent Parton Distribution Functions (TMDs) were extensively studied at COMPASS using Semi-Inclusive Deep Inelastic Scattering measurements. In 2015, the Drell-Yan measurements with a negative pion beam interacting...

We present a survey of electromagnetic form factors and mass spectra of light baryons obtained within a Poincaré covariant Faddeev equation framework, the ingredients of which are constrained by calculations in continuum QCD.

In 1979, Feynman and Veneziano had already proposed that multiparticle production can have a fractal structure, what could explain the complexity of the multiparticle processes in high energy collisions. In the next decades, multiparticle fractality was observed through the intermittence that appears in many distributions measured in different laboratories. Almost two decades before that,...

The compatibility of the results from the Gribov-Zwanziger tree level prediction and lattice simulations, using large statistical ensembles, for the Landau gauge gluon propagator are investigated, thereby complementing earlier work using small-scale statistics. Our results show that the data is well described by the tree level estimate only up to momenta p≲1 GeV while clearly favoring the...

High-energy heavy-ion collisions provide a unique opportunity to study the properties of the hot and dense strongly-interacting system composed of deconfined quarks and gluons – the quark-gluon plasma (QGP) - in a laboratory conditions. The formation of a QGP is predicted by lattice QCD calculations as a crossover transition from hadronic matter (at zero baryochemical potential) and it is...

Laboratories like JLAB, COMPASS and HERMES have dedicated programs focused on the investigations of Semi-inclusive DIS processes. Their results gives an opportunity to reconstruct the 3D structure of the hadron, in particular, the Transverse Momentum Distributions (TMDs). Their findings can give insights about the internal hadron dynamics as quark-gluon correlations and final-state...

Neutron stars are unique cosmic laboratories for the exploration of matter under extreme conditions of density and neutron-proton asymmetry. Due to their enormous dynamic range, neutron stars display a myriad of exotic states of matter that are impossible to recreate under normal laboratory conditions. In this presentation I will discuss how the combination of nuclear physics insights...

In a first lecture we will consider the complexity of the conventional Nucleon-Nucleon interaction either in the traditional meson exchange or in the EFT framework.

The following lectures aim to be an introductory course to the Lattice techniques used to solve the Quantum Field Theory in a non perturbative regime, with special interest in the Quantum Chromodynamics (QCD).

This activity started...

The origin of the elements has been one of the most fascinating questions scientists have tried to give an answer to in the last 7 decades. The formation of light elements in the primordial universe and heavier elements, both in the intergalactic environment and in the astrophysical sources, occurs through nuclear reactions. We can say that nuclear processes are responsible for the production...

The discrete Efimov scaling behavior, well-known in the low-energy spectrum of three-body bound systems for large scattering lengths (unitary limit), is identified in the energy dependence of atom-molecule elastic cross-section in mass imbalanced systems. That happens in the collision of a heavy atom with mass $m_H$ with a weakly-bound dimer formed by the heavy atom and a lighter one with mass...
