Query: Comparing standard distribution and its Tsallis form of transverse
  momenta in high energy collisions   In this paper, the experimental (simulated) transverse momentum spectra of
negatively charged pions produced at mid-rapidity in central nucleus-nucleus
collisions at the Heavy Ion Synchrotron (SIS), Relativistic Heavy Ion Collider
(RHIC), and Large Hadron Collider (LHC) energies obtained by different
collaborations are selected by us to investigate, where a few simulated data
are taken from the results of FOPI Collaboration who uses the IQMD transport
code based on Quantum Molecular Dynamics. A two-component standard distribution
and the Tsallis form of standard distribution are used to fit these data in the
framework of a multisource thermal model. The excitation functions of main
parameters in the two distributions are analyzed. In particular, the effective
temperatures extracted from the two-component standard distribution and the
Tsallis form of standard distribution are obtained, and the relation between
the two types of effective temperatures is studied.
