Statistical Behavior of Lepton Pair Spectrum in the Drell-Yan Process and Signal from Quark-Gluon Plasma in High-Energy Collisions

Table 2

Values of parameters and in the Lévy-Tsallis function (solid curves), , , and in the two-component Erlang distribution (dashed curves), as well as and in the Hagedorn function (dotted curves) in Figures 2–4. The is for each fit. The ndof is for the fits of the two-component Erlang distribution. For the fits of the Lévy-Tsallis function and Hagedorn function, the ndof needs one more. For Figures 4(a) and 4(b), different ranges are included. and for Figures 2 and 4, as well as and for Figure 3, which are not listed in the table.
