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

Figure 1

Transverse momentum spectra of produced in central Au-Au collisions at (circles) and 2.52 GeV (squares). The symbols represent the experimental data of the FOPI Collaboration [41] measured in midrapidity range and the last eight circles represent the simulated data of the IQMD transport code [45] which is based on Quantum Molecular Dynamics [46]. The statistical errors are smaller than the size of symbols. The dashed and solid curves are the results fitted by the two-component standard distribution and the Tsallis form of standard distribution, respectively.
