On Jψ and Υ Transverse Momentum Distributions in High Energy Collisions

Abstract EN

The transverse momentum distributions of final-state particles are very important for high energy collision physics.

In this work, we investigate J/ψ and Υ meson distributions in the framework of a particle-production source, where Tsallis statistics are consistently incorporated.

The results are in good agreement with the experimental data in p-p and p-Pb collisions at LHC energies.

The temperature of the emission source and the nonequilibrium degree of the collision system are extracted.
