Comparing Multicomponent Erlang Distribution and Lévy Distribution of Particle Transverse Momentums

Table 1

Parameter values for the two kinds of curves in Figure 1. The values of 𝜒²/dof and extracted temperatures are given. The errors for 𝑚₁, 𝑚₂, and 𝑛 can be neglected, and the relative errors for other parameters are less than 10%.
