【 摘 要 】

The transverse momentum $p_T$ spectra of both hadrons and jets produced in $pp$ collisions at beam energies from hundreds GeV to a few TeV exhibit power-law behavior of $1/p_T^n$ at high $p_T$, with similar power indices n. The respective nonextensivity parameters for transverse momenta distributions and the global nonextensivity parameter obtained from multiplicities are compared. In particular, data on kaon to pion (charged particles) multiplicity ratio are analyzed, assuming that the reaction occurs in some nonextensive environment. The values of the corresponding nonextensivity parameters were found to be similar, strongly indicating the existence of a common mechanism behind all these observables.
