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. [...]

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. [...]

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. [...]

Predictions on global properties in O+O collisions at the Large Hadron Collider 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)
Oxygen ($^{16}$O) ions are planned to be injected at the Large Hadron Collider (LHC) in its next runs, and a day of physics run is anticipated for O+O collisions at $\sqrt{s_{\rm{NN}}}$ = 7 TeV. As the system size of O+O collisions has the final state multiplicity overlap with those produced in pp, p+Pb and Pb+Pb collisions, the study of global properties in O+O collisions may provide a deeper insight into the heavy-ion-like behavior observed in small collision systems and its similarities/differences with a larger system like Pb+Pb collisions.

Event topology and global observables in heavy-ion collisions at the Large Hadron Collider
/ Prasad, Suraj (Indian Inst. Tech., Kanpur) ; Mallick, Neelkamal (Indian Inst. Tech., Kanpur) ; Behera, Debadatta (Indian Inst. Tech., Kanpur) ; Sahoo, Raghunath (Indian Inst. Tech., Kanpur ; CERN) ; Tripathy, Sushanta (INFN, Bologna)
Particle production and event topology are very strongly correlated in high-energy hadronic and nuclear collisions. Event topology is decided by the underlying particle production dynamics and medium effects. [...]
