Decoding Chemical Potential Effects at the Kinetic Freeze-Out through Tsallis Non-Extensive Statistics at the LHC / Pradhan, Girija Sankar (Indian Inst. Tech., Indore) ; Sahu, Dushmanta (Indian Inst. Tech., Indore) ; Rath, Rutuparna (INFN, Bologna) ; Sahoo, Raghunath (Indian Inst. Tech., Indore) ; Cleymans, Jean (UCT-CERN Res. Ctr. ; Cape Town U.)
At the LHC energies near chemical freezeout, the chemical potential is expected to be zero due to particles and antiparticles being produced almost in equal numbers. However, considering the same case at the kinetic freezeout temperature is not trivial. [...]

Multiplicity Dependence of Non-extensive Parameters for Strange and Multi-Strange Particles in Proton-Proton Collisions at $\sqrt{s}= 7$ TeV at the LHC / Khuntia, Arvind (Indian Inst. Tech., Indore) ; Tripathy, Sushanta (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore) ; Cleymans, Jean (UCT-CERN Res. Ctr. ; Cape Town U.)
The transverse momentum ($p_{\rm T}$) spectra in proton-proton collisions at $\sqrt{s}$ = 7 TeV, measured by the ALICE experiment at the LHC are analyzed with a thermodynamically consistent Tsallis distribution. The information about the freeze-out surface in terms of freeze-out volume, temperature and the non-extenisivity parameter, $q$, for $K^{0}_{S}$, $\Lambda+\bar{\Lambda}$, $\Xi^{-}+\bar{\Xi}^{+}$ and $\Omega^{-}+\bar{\Omega}^{+}$ are extracted by fitting the $p_{\rm T}$ spectra with Tsallis distribution function. [...]

Event multiplicity, transverse momentum and energy dependence of charged particle production, and system thermodynamics in $pp$ collisions at the Large Hadron Collider / Rath, Rutuparna (Indian Inst. Tech., Indore) ; Khuntia, Arvind (Cracow, INP) ; Sahoo, Raghunath (Indian Inst. Tech., Indore) ; Cleymans, Jean (UCT-CERN Res. Ctr.)
In the present work, we study the recent collision energy and multiplicity dependence of the charged particle transverse momentum spectra as measured by the ALICE collaboration in $pp$ collisions at $\sqrt{s}$ = 5.02 and 13 TeV using the non-extensive Tsallis distribution and the Boltzmann-Gibbs Blast Wave (BGBW) model. A thermodynamically consistent form of the Tsallis distribution is used to extract the kinetic freeze-out parameters from the transverse momentum spectra of charged particles at mid-rapidity. [...]

Tsallis Statistics in High Energy Physics: Chemical and Thermal Freeze-Outs / Cleymans, Jean (UCT-CERN Res. Ctr.) ; Wellington Paradza, Masimba (UCT-CERN Res. Ctr. ; Cape Peninsula U. of Tech.)
We present an overview of a proposal in relativistic proton-proton ($pp$) collisions emphasizing the thermal or kinetic freeze-out stage in the framework of the Tsallis distribution. In this paper we take into account the chemical potential present in the Tsallis distribution by following a two step procedure. [...]

Hadron gas in the presence of a magnetic field using non-extensive statistics: A transition from diamagnetic to paramagnetic system / Pradhan, Girija Sankar (Indian Inst. Tech., Indore) ; Sahu, Dushmanta (Indian Inst. Tech., Indore) ; Deb, Suman (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore ; CERN)
Non-central heavy-ion collisions at ultra-relativistic energies are unique in producing magnetic fields of the largest strength in the laboratory. Such fields being produced at the early stages of the collision could affect the properties of Quantum Chromodynamics (QCD) matter formed in the relativistic heavy-ion collisions. [...]

Global properties in O+O collisions at $\sqrt{s_{NN}}= 7 $ TeV using a multi-phase transport model / Behera, Debadatta (Indian Inst. Tech., Indore) ; Mallick, Neelkamal (Indian Inst. Tech., Indore) ; Tripathy, Sushanta (INFN, Bologna) ; Prasad, Suraj (Indian Inst. Tech., Indore) ; Mishra, Aditya Nath (Wigner RCP, Budapest) ; Sahoo, Raghunath (Indian Inst. Tech., Indore ; CERN)
The primary goal of ultra-relativistic heavyion collision experiments is to study the nuclear matter and the phase transition of hadronic matter to quark-gluon plasma (QGP) under extreme conditions of high temperature and energy density. Results from small collision systems act as baseline for those results. [...]
