An Extensive Analysis of Tsallis Statistics: π±, K± Mesons, and pp¯ Baryon in Inelastic pp Collisions

Abstract

This study explores the inelastic doubly differential transverse momentum spectra of the primary charged particles, (π++π−), (K++K−) and (pp¯), as a function of observables associated with underlying event (UE) at s=13TeV. The particle production is measured on the basis of different angular regions like toward, transverse and away, elucidated with respect to the direction of leading particle of an event. To study the thermal freeze-out parameters, the non-extensive Tsallis distribution function is used to extract the temperature Teff and chemical potential μ, which provide a basis to explain the QCD matter. The Tsallis distribution function describes transverse momentum spectra in pseudorapidity region of |η|<0.8. It is observed that effective temperature Teff changes from away to towards and forward region.
