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. [...]

Bose-Einstein condensation of pions in proton–proton collisions at the Large Hadron Collider using non-extensive Tsallis statistics / Deb, Suman (Indian Inst. Tech., Kanpur) ; Sahu, Dushmanta (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore ; CERN) ; Pradhan, Anil Kumar (Indian Inst. Tech., Indore)
The possibility of formation of Bose-Einstein Condensation (BEC) is studied in $pp$ collisions at $\sqrt s$ = 7 TeV at the Large Hadron Collider. A thermodynamically consistent non-extensive formulation of the identified hadron transverse momentum distributions is used to estimate the critical temperature required to form BEC of charged pions, which are the most abundant species in a multi-particle production process in hadronic and nuclear collisions.

Investigating radial-flow-like effects via pseudorapidity and transverse spherocity dependence of particle production in pp collisions at the LHC / R, Aswathy Menon K. (Indian Inst. Tech., Indore) ; Prasad, Suraj (Indian Inst. Tech., Indore) ; Tripathy, Sushanta (CERN) ; Mallick, Neelkamal (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore)
Recent observations of quark-gluon plasma (QGP) like signatures in high multiplicity proton-proton (pp) collisions, have compelled the heavy-ion physics community to re-examine the pp collisions for proper baseline studies. [...]

Probing strangeness with event topology classifiers in pp collisions at the LHC with rope hadronization mechanism in PYTHIA / Prasad, Suraj (Indian Inst. Tech., Indore) ; Sahoo, Bhagyarathi (Indian Inst. Tech., Indore) ; Tripathy, Sushanta (CERN) ; Mallick, Neelkamal (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore)
In relativistic heavy-ion collisions, the formation of a deconfined and thermalized state of partons, known as quark-gluon plasma, leads to enhanced production of strange hadrons in contrast to proton-proton (pp) collisions, which are taken as baseline. [...]

Characterizing Proton-Proton Collisions at the Large Hadron Collider with Thermal Properties / Sahu, Dushmanta (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore ; CERN)
High-multiplicity proton-proton (pp) collisions at the Large Hadron Collider (LHC) energies have created a new domain of research to look for a possible formation of quark-gluon plasma in these events. In this paper, we estimate various thermal properties of the matter formed in pp collisions at the LHC energies, such as mean free path, isobaric expansivity, thermal pressure, and heat capacity using a thermodynamically consistent Tsallis distribution function. [...]

Possible formation of a perfect fluid in $pp$, $p$–Pb, Xe–Xe and Pb–Pb collisions at the Large Hadron Collider energies: a color string percolation approach / Sahu, Dushmanta (Indian Inst. Tech., Madras ; Indian Inst. Tech., Kanpur) ; Tripathy, Sushanta (Indian Inst. Tech., Madras ; Indian Inst. Tech., Kanpur) ; Sahoo, Raghunath (Indian Inst. Tech., Madras ; Indian Inst. Tech., Kanpur ; Indian Inst. Tech., Indore ; CERN) ; Tiwari, Swatantra Kumar (Unlisted, IN ; Bihar U.)
Isothermal compressibility ($\kappa_{\rm T}$) is an important thermodynamic observable which gives information about the deviation of a system from perfect fluid behavior. In this work, for the first time we have estimated the isothermal compressibility of QCD matter formed in high energy hadronic and nuclear collisions using color string percolation model (CSPM), where we investigate the change in $\kappa_{\rm T}$ as a function of final state charged particle multiplicity and initial percolation temperature across various collision species.

Estimation of Impact Parameter and Transverse Spherocity in heavy-ion collisions at the LHC energies using Machine Learning / Mallick, Neelkamal (Indian Inst. Tech., Indore) ; Tripathy, Sushanta (INFN, Bologna) ; Mishra, Aditya Nath (Wigner RCP, Budapest) ; Deb, Suman (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore ; CERN)
Recently, machine learning (ML) techniques have led to a range of numerous developments in the field of nuclear and high-energy physics. In heavy-ion collisions, the impact parameter of a collision is one of the crucial observables which has a significant impact on the final state particle production. [...]

Exploring the effect of hadron cascade-time on particle production in Xe+Xe collisions at $\sqrt {s_{NN}}$ = 5.44 TeV through a multi-phase transport model / Pradhan, Girija Sankar (Indian Inst. Tech., Indore) ; Rath, Rutuparna (Indian Inst. Tech., Indore) ; Scaria, Ronald (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore ; CERN)
Heavy-ion collisions at ultra-relativistic energies provide extreme conditions of energy density and temperature to produce a deconfined state of quarks and gluons. Xenon (Xe) being a deformed nucleus further gives access to the effect of initial geometry on final state particle production. [...]

Charmonium suppression in ultra-relativistic proton–proton collisions at LHC energies: a hint for QGP in small systems / Singh, Captain R. (Indian Inst. Tech., Indore) ; Deb, Suman (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore ; CERN) ; Alam, Jan-e (Calcutta, VECC)
Proton-proton ($pp$) collision has been considered as a baseline to study the system produced in relativistic heavy-ion (AA) collisions with the basic assumption that no thermal medium is formed in $pp$ collisions. This warrants a cautious analysis of the system produced in $pp$ collisions at relativistic energies.In this work we investigate the charmonium suppression in $pp$ collisions at $\sqrt{s} = 5.02, 7$ and $13$ TeV energies. [...]

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. [...]
