Comparing Standard Distribution and Its Tsallis Form of Transverse Momenta in High Energy Collisions

Table 1

Values of free parameters for the two-component standard distribution, free parameters ( and ) for the Tsallis form of standard distribution, derivative parameters ( and ), , and dof corresponding to the fits in Figures 14, as well as values of slope and intercept corresponding to the fits of linear functions in Figures 5 and 6. As a preliminary result, the values of for the first and second standard distribution and the Tsallis form are assumed to be the same. The units of effective temperatures and chemical potential are in GeV.
