Charmed hadrons are powerful probes to investigate the properties of the state of strongly-interacting matter with very high temperature and energy density formed in ultra-relativistic heavy-ion collisions, known as the Quark-Gluon Plasma (QGP). Because of their large masses, charm quarks are produced in the early stages of the collisions and propagate through the high-density medium...
The study of open charm meson production provides an efficient tool for detailed investigations of the properties of hot and dense matter formed in nucleus-nucleus collisions. The interpretation of the existing data from the CERN SPS suffers from a lack of knowledge on the total charm production rate. To overcome this limitation the heavy-ion programme of the NA61/SHINE experiment at CERN SPS...

Hadrons carrying heavy quarks, i.e. charm or bottom, are important
probes of the hot and dense medium created in relativistic heavy-ion
collisions. Heavy quark-antiquark pairs are mainly produced in initial ...
Direct photons are a very important probe to study the properties of the medium created by heavy ion collisions, since they are produced throughout the collision history and carry out information about the medium at the point of their production, without strong interaction. While high pT direct photons originating from initial hard scattering serve as a test for pQCD, low pT photons contain...
The NA61/SHINE experiment studies hadron production in hadron-hadron, hadron-nucleus and nucleus-nucleus collisions. The physics programme includes the study of the onset of deconfinement and search for the critical point as well as reference measurements for neutrino and cosmic ray experiments. For strong interactions, future plans are to extend the programme of study of the onset of...
Particles resultant from heavy ion collisions at $\sqrt{s_{NN}} = 2.76\mathrm{TeV}$ are mapped in a Mollweide type of projection. We decompose the particles' distribution in Spherical Harmonics and finally calculate its angular power spectrum. In practice,detector deficiencies and lack of full pseudorapidity ($\eta$) coverage introduce artificial structures to the power spectrum, which are...
We present the latest results on the production of strange and multi-strange hadrons in pp and Pb--Pb collisions with ALICE at the LHC energies of $\sqrt{\mathrm{s}}$ = 13 TeV and $\sqrt{s\
_{\mathrm{NN}}}$ = 5.02 TeV. Strangeness production measurements are powerful tools for the study of the thermal properties of the deconfined state of QCD matter, the Quark-Gluon Plasma.
Thanks to its...
We have studied pT distributions of the invariant inclusive cross sections for the primary charged particles produced in p-Pb collisions at LHC energies with pT in the interval of: 0.5 - 20 GeV/c using HIJING and UrQMD models. We observed that both ALICE Experimental data could not be described properly by HIJING and UrQMD models, But for the particles with pT > 5 GeV/c and in the...
Approximately 1 $\mu$s after the Big Bang, the universe was in the state of a Quark-Gluon Plasma (QGP), an ultra hot and dense state of matter consisting of quarks and gluons. With the Large Hadron Collider (LHC) at CERN, in Switzerland, the properties of the QGP are studied by recreating this state of matter in collisions of lead ions. Studies of collisions of protons with protons or lead...
The strong coupling $\alpha_s$ is one of the fundamental parameters of the Standard Model (SM). Its precise knowledge is of crucial importance to fully exploit the potential of the LHC and future experiments in testing the SM and constrain New Physics. However, an accurate determination of $\alpha_s$, i.e. comfortably below the percent level, faces many difficulties. There are several...
Heavy flavor quarks are unique tools for studying the properties of the Quark Gluon Plasma (QGP) produced in high-energy nuclear collisions. Since heavy quarks are predominantly created in the initial hard scatterings in a heavy-ion collision, they can access the information of the early time dynamics. In this talk we will present pT and centrality dependences of the production and elliptic...
We review our studies of spectator-induced electromagnetic (EM) effects on charged pion and kaon emission in nucleus-nucleus collisions at CERN SPS and RHIC BES energies. These are found to consist in (1) the breaking of isospin symmetry for spectra of fast pions in peripheral collisions, (2) centrality dependent distortions in ratios of emitted $\pi^+/\pi^-$ and $K^+/K^-$ in the final state,...
Numerical monte carlo study of lattice discretized QCD is the only
non-perturbative tool available for calculation of the equation of
state of strongly interacting matter from QCD at not-too-high
temperatures. Unfortunately, these numerical tools are not directly
applicable at finite baryon densities, as is required for, e.g., the
beam energy scan studies.
Using the method of Taylor...
