Abstract
This work focuses on the study of identified (, , p, and ), strange hadrons (, Λ, ), recorded by CMS, and light nuclei and their anti-nuclei (d, , t, , 3He and ), recorded by ALICE, at , 2.76 TeV, 7 TeV and 13 TeV in pp collision at mid rapidities. The p T distributions of these particles are analyzed using the Tsallis model, which fits the experimental data very well. Several important parameters for studying the characteristics of the medium produced during such collisions are extracted. The effective temperature (T) increases monotonically with increasing particle mass and also with increasing collision energy. The non-extensivity parameter (q) decreases with the mass of the particle. For heavier particles, greater T and smaller q mean that they decouple early from the system and attain equilibrium quickly compared to lighter ones. Furthermore, with an increase in collision energy, the multiplicity parameter N 0 increases.
