## Abstract

The transverse momentum distributions of final-state particles are very important for high-energy collision physics. In this work, we investigate and meson distributions in the framework of a particle-production source, where Tsallis statistics are consistently integrated. The results are in good agreement with the experimental data of proton-proton ( ) and proton-lead ( -Pb) collisions at LHC energies. The temperature of the emission source and the nonequilibrium degree of the collision system are extracted.
