Multiplicity Dependence of the Freeze-Out Parameters in Symmetric and Asymmetric Nuclear Collisions at Large Hadron Collider Energies

Strange hadron transverse momentum spectra are analyzed in symmetric (Formula presented.) and (Formula presented.) and asymmetric (Formula presented.) collision systems for their dependence on rapidity and event charged-particle multiplicity. The thermodynamically consistent Tsallis models with and without flow velocity are used to reproduce the experimental data, extracting the freeze-out parameters to gain insights into the underlying physics of the collision processes by looking into the parameters change with different multiplicities, particle types, and collision geometries. We found that with an increase in the event multiplicity, the average transverse flow velocity, effective, and kinetic freezeout temperatures increase, with heavier strange particle species exhibiting a more significant increase. The value of the non-extensivity parameter decreases with an increase in the multiplicity of the particles. For heavier particles, larger (Formula presented.) and (Formula presented.) and smaller q have been observed, confirming the quick thermalization and equilibrium for massive particles. Furthermore, the differences in parameter values for particle species are more significant in (Formula presented.) and (Formula presented.) collisions than in (Formula presented.) collisions. In addition, in symmetric (Formula presented.) and (Formula presented.) collisions, parameter values ((Formula presented.)) show more significant shifts for heavier particles compared to the lighter ones. In contrast, in asymmetric (Formula presented.) collisions, both heavier and lighter particles display uniform linear progression.
