There have been recent updates to the three global PDF fits (CT, MSHT and NNPDF), all using significant amounts of data from the LHC, in addition to the non-LHC data sets that formed the core of previous iterations. Given the impact of the LHC data on the global PDF fits, and the impact that the new PDFs will have on physics comparisons at the LHC, it is crucial to perform a benchmarking among...
Semi-visible jets arise in strongly interacting dark sectors, where parton evolution includes dark sector emissions, resulting in jets overlapping with missing transverse momentum. The implementation of semi-visible jets is done using the Pythia Hidden valley module to duplicate the dark sector showering. In this work, several jet substructure observables have been examined to compare...
The light-front holography or light-front AdS/QCD is defined as a connection between light-front QCD and the description of hadronic modes on AdS spacetime. This relation, inspired in the AdS/CFT correspondence, has shown improvements in analytic solutions in the hadron physics regime.
We are motivated by the light-front AdS/QCD prediction on a general form of two particle bound state wave...
Multiparticle correlations measurements in even the smallest collision systems are consistent with predictions from viscous relativistic hydrodynamics calculations. However, these hydrodynamics calculations use a continuum extrapolated---i.e. infinite volume---equation of state. For the modest temperature probed in these small collisions, the controlling dimensionless product of the...
Charged pions, which obviously carry no baryon number, possess, however, a nontrivial baryonic structure, stemming from the isospin breaking with the up and down quark mass splitting and the EM effects. We obtain estimates for the corresponding pion baryonic (vector isoscalar) form factor in two ways: from simple constituent quark models on one hand, and from vector meson dominance model fits...
Medium-induced gluon radiation is known to be an important tool to extract the properties of the QGP created in heavy-ion collisions. I will use a recent approach to evaluate the full in-medium gluon emission spectrum, including the resummation of all multiple scatterings, to analyze the validity of the usually employed analytical approximations. More specifically, by using this all-order...
The study of hadronic jet substructure has become a burning topic in recent years, bringing to a high request for designing precise observable to understand it. A novel observable, called the "Jet Colour Ring", aims at constructing a colour tagger, able to discriminate the decay of a colour-singlet into two jets from a two-jet background in a different colour configuration. The Jet Colour Ring...
An important observable for studying partonic energy loss in high energy nucleus-nucleus collisions is the jet fragmentation function. Detailed investigation of low momentum (10-60 GeV) jet fragmentation functions may complement previous studies by providing more information on energy loss. The main difficulty in studying low momentum jets in heavy ion collisions is the presence of a...
In past many studies are done on cosmic ray which are said to be messengers of universe but no one yet think to study the effects when there is a meteor showers. It opens a new window to study more about the universe or allows us to see the universe in a different way. Most of stratosphere conditions can be created in laboratories like Temperature, Pressure, humidity and even some radiations...
Collective phenomena in heavy-ion collisions are very sensitive to initial geometry including nuclei deformation effects. Recent hydrodynamic calculations and preliminary data by the STAR Collaboration show such deformation effects can be probed by studying the correlation between event-wise average transverse momentum $[p_T]$ and harmonic flow $v_n$. In particular, due to prolate shape of the...
In the RHIC Beam Energy Scan program, gold nuclei are collided with different collision energies in the range from few to 62.4 GeV. The goals of the program are to explore the onset of QGP creation, locate the critical point of QCD and study dense baryon matter.
In this talk, we report on the first application of 3D Monte Carlo Glauber (GLISSANDO2) and TrENTO p=0 initial states for 3D...
Droplets of quark-gluon plasma produced in heavy-ion collisions rapidly evolve expanding and cooling. During considerable part of this dynamics the system can be described within relativistic hydrodynamics. Recently, there were some attempts to include effects of the medium motion to the jet energy loss and jet modification calculations in a variety of models. Here we will present the first...
Two-particle transverse momentum correlator is a powerful technique for understanding the dynamics of relativistic heavy-ion collisions. Among these, the transverse momentum correlator $G_{2}\left(\Delta\eta,\Delta\varphi\right)$ is of particular interest for its potential sensitivity to the shear viscosity per entropy density $\eta/s$ of the quark-gluon plasma formed in heavy-ion...
In the past years, significant progress has happened in high-energy nuclear physics models. A more robust and quantitative picture has replaced the qualitative descriptions of heavy nuclei collisions in the earlier days, enabling us to have a clearer picture of different stages of a heavy-ion collision. These models typically have $O(10)$ free parameters that are tuned by Bayesian analysis in...
