Description
High-energy collisions allow us to study the behaviour of matter at high temperature and density. Various experimental signatures suggest that a new state of matter called Quark-Gluon Plasma (QGP) is produced in heavy-ion collisions. However, recent results suggest that high-multiplicity $p$+$p$ collisions might also be able to produce QGP droplets. Therefore, there is a pressing need to gain deeper insights into $p$+$p$ collisions to understand the properties of the produced system. Tsallis statistics is a non-extensive statistical mechanics framework that has been used to successfully describe a wide range of complex systems, including high-energy collisions. We use thermodynamically consistent Tsallis statistics to study the charged hadron spectra from $p$+$p$, $p$+Pb, Xe+Xe, and Pb+Pb collisions at the LHC.
In this talk, we will show the system size dependence of various thermodynamic variables at the kinetic freeze-out (KFO) surface. Our results show that the rate of increase (or decrease) with system size of various thermodynamic variables is more rapid in small systems such as $p$+$p$ and $p$+Pb collisions than in large systems such as Xe+Xe and Pb+Pb collisions. Moreover, we also find that the magnitudes of different thermodynamic variables in high-multiplicity $p$+$p$ collisions are comparable to those in peripheral heavy-ion collisions.
