Hadron resonances

poster presentation

In this work we report the first results on $K^{*}(892)^{\pm}$ and $\phi$(1020) production in pp collisions at $\sqrt{s}$ = 5.02 TeV with the ALICE detector. The hidden strangeness $\phi$-meson is reconstructed at mid-rapidity via its hadronic decay channel $\phi \rightarrow$ K$^{+}$K$^{-}$, by employing different techniques, without and with kaon identification using the information from the...

Strangeness production at low baryon densities

poster presentation

Observables sensitive to the vorticity allow us to study the fundamental property of the hot and dense nuclear matter created in high-energy nuclear collisions. 
Global polarization parameters of identified particles can be extracted from the 
azimuthal distribution of particles with respect to the event plane. The spin alignment of vector meson such as $\phi$ meson and $K^{\star}$ could be...

Small systems (pA)

poster presentation

Measurements of azimuthal correlations can be used to probe the anisotropy of produced particles, and are therefore sensitive probes of the initial conditions of the collision.
Moreover, the measurement of anisotropy in p-Pb collisions may provide additional insights into the possible collectivity
in this small system originally motivated by the measurements of multi-particle azimuthal...

223. Comparing various approaches to chiral vortical effect

Mr George Prokhorov (Dubna, JINR)

11/07/2017, 16:00

poster presentation

Different aspects of chiral phenomena are considered on the basis of comparison of generalized thermodynamic distribution function and quantum-field calculation of one-loop triangle diagram. The consequences for particle polarization in heavy ion collisions are discussed.

224. Correlation femtoscopy studies at NICA and STAR energies within a viscous hydrodynamic + cascade model

Pavel Batyuk (Joint Institute for Nuclear Research (RU))

11/07/2017, 16:00

poster presentation

Correlation femtoscopy allows one to measure the space-time characteristics of particle production in relativistic heavy-ion collisions due to the effects of quantum statistics and final state interactions. The main features of the femtoscopy measurements at top RHIC and LHC energies are considered as a manifestation of strong collective flow and well interpreted within hydrodynamic models...

Freeze-out, hadronisation and statistical models

poster presentation

We investigate the shear viscosity ($\eta$) and electrical conductivity ($\sigma_{\rm{el}}$)
of the anisotropic quark-gluon plasma (QGP) medium.
Relativistic Boltzmann kinetic equation has been solved
in the relaxation time approximation to calculate the shear viscosity and electrical conductivity. We use the quasiparticle model to estimate these transport coefficients and discuss the...

60. First results of $\rm{K^{*}(892)^{\pm}}$ production in pp collisions at $\sqrt{s} = \rm{13} \hspace{0.15 cm} \rm{TeV}$ with ALICE at LHC

Kunal Garg (Universita e INFN, Catania (IT))

11/07/2017, 16:00

Hadron resonances

poster presentation

The study of hadronic resonances plays an important role both in elementary and in heavy-ion collisions as it can provide information about strangeness production and the hadronic phase of the system. Since the lifetimes of short-lived resonances are comparable with the lifetime of the fireball formed in heavy-ion collisions, regeneration and rescattering effects can modify the measured yield...

82. Heavy-flavour hadron decay electron correlations in p-Pb and Pb-Pb collisions at $\sqrt{{s}_{\rm{NN}}} = 5.02$ TeV with the ALICE detector

Deepa Thomas (University of Texas (US))

Heavy-flavour (open and hidden)

poster presentation

Heavy quarks (charm and beauty) are unique probes used to understand the properties of the QCD medium produced in ultra-relativistic heavy-ion collisions. Due to their large masses, they are created in the early stages of the collisions and experience the full evolution of Quark-Gluon Plasma (QGP). They interact with its consitutents and lose energy as they travel through the medium. Heavy...

35. J/$\psi$ measurements in pp collisions at $\sqrt{s}$ = 13 TeV using EMCal-triggered events with ALICE at LHC

Dr Cristiane Jahnke (Technische Universitaet Muenchen (DE))

11/07/2017, 16:00

Heavy-flavour (open and hidden)

poster presentation

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...

73. K*(892)0 Production in pp Collisions with ALICE Detector at the LHC

Mr Arvind Khuntia Khuntia (IIT Indore), Dr Raghunath Sahoo (IIT Indore)

11/07/2017, 16:00

Hadron resonances

poster presentation

The lifetimes of short-lived hadronic resonances are comparable to the one of the hadronic phase of the medium produced in high-energy collisions. Thus, these resonances are sensitive to the re-scattering and regeneration processes in the time interval between the chemical and kinetic freeze-out, which might affect the resonance yields. The measurements in pp collisions are used as a...

Freeze-out, hadronisation and statistical models

poster presentation

In the high-energy heavy-ion physics community the FORTRAN based HIJING Heavy Ion Jet Interaction Generator code is commonly used, originally developed by Xin-Nian Wang and Miklos Gyulassy [1]. Although it was intended to describe the heavy-ion collisions occurring at RHIC energies, it has still many applications with todays higher collision energies. However, the technological advancement...

11/07/2017, 16:00

Heavy-flavour (open and hidden)

poster presentation

Measurements of open heavy-flavour production in p--Pb collisions at the Large Hadron Collider (LHC) allow the study of cold-nuclear matter effects, such as shadowing, $k_T$ broadening and initial-state energy loss. Heavy quarks (charm and beauty) are a valuable probe for the Quark-Gluon Plasma created in Pb--Pb collisions, since they are produced in hard scattering processes in the initial...

Heavy-flavour (open and hidden)

poster presentation

Proton-proton collisions at the LHC are an excellent source of experimental data that allow us to test particle-production processes calculable with perturbative QCD. Heavy quarks (charm and beauty) are an interesting probe because, due to their large masses, the energy scales involved in their production are large. Therefore their production cross section can be calculated with perturbative...

Small systems (pA)

poster presentation

Measurements of identified particle production as a function of the event multiplicity in proton-proton (pp) and proton-nucleus collisions have recently gained interest for the investigation of particle production mechanisms in small systems and how they relate to those in the larger system created in nucleus-nucleus collisions.
In particular, recent results reported by the ALICE Collaboration...

Freeze-out, hadronisation and statistical models

poster presentation

Measurements of particle production in high-multiplicity pp collisions are crucial for the understanding of the collective-like features observed in small systems and reminiscent of those present in heavy-ion collisions. The ALICE detector, with its excellent tracking and particle identification capabilities, provides unique possibilities for the systematic study of light-flavour hadrons at...

11/07/2017, 16:00

poster presentation

We report on the results on the dynamical modelling of cluster formation with the new combined PHQMD+FRIGA model at Nuclotron and NICA energies. The FRIGA clusterisation algorithm, which can be applied to the transport models, is based on the simulated annealing technique to obtain the most bound configuration of fragments and nucleons. The PHQMD+FRIGA model is able to predict isotope yields...

QCD phase diagram (BES)

poster presentation

Knowing the initial geometry and fluctuations in heavy-ion collisions has recently been shown to have important consequences on interpreting the data from the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) experiments. It is also believed that measurement of higher order flow coefficients and their fluctuations can substantially improve the constraints on
the...

112. Study of non-extensive parameters in transverse momentum spectra of hadrons

Prof. Barnafoldi Gergely (Hungarian Academy of Sciences (HU))

11/07/2017, 16:00

Freeze-out, hadronisation and statistical models

poster presentation

Since firstly proposed by C. Tsallis, the q-non-extensive statistics has been of great interest both experimentally and theoretically. One of the most important applications is the non-extensive effects on the transverse momentum (pT) spectra of both strange and non-strange particles in heavy-ion collisions, where it shows a power-law tail for the large pT range.

To clarify not only the...

11/07/2017, 16:00

Small systems (pA)

poster presentation

Recent measurements performed in high-multiplicity proton-proton (pp) and proton-lead (p-Pb) collisions have shown features that are reminiscent of those observed in lead-lead (Pb-Pb) collisions.
The origin of these features is, however, still controversial, with collectivity, initial state effects and multipartonic correlations all possibly contributing.
The pp measurements have in the past...

31. Unified description of $p_{T}$ dependent $\Upsilon$ (1S) suppression in hot QCD matter

Heavy-flavour (open and hidden)

poster presentation

Bottomonium are produced in the heavy ion collisions and their production is modified compared with elementary collisions. This modification in the production of bottomonia happens due to the presence of hot and dense QCD matter, named as quark-gluon plasma (QGP) formed in ultra relativistic heavy ion collisions. We
present here a comprehensive model based on color screening, collisional...
