Comparing Multicomponent Erlang Distribution and Lévy Distribution of Particle Transverse Momentums

Figure 1

Transverse momentum spectrums of final-state particles produced in Cu-Cu and Au-Au collisions at √𝑠_𝑁𝑁=0.2 TeV. The symbols represent experimental data of the STAR Collaboration [11]. The solid and dashed curves represent results calculated by the multicomponent Erlang distribution and the Lévy distribution, respectively, (a), (b), (c), (d), (e), and (f) correspond to different final-state particles and collisions.
