Similar to the previous observables, the thermal/HadRSc model improves the description of the measured mT spectra, compared to the Gaussian/HadRSc, as π− obtains larger mT values due to expansion flow. It is interesting to notice that large deviation of thermal/HadRSc from Gaussian/HadRSc...
Epos and Urqmd model predictions show a slope that is more similar to p+p interactions and less steep than for Ar+Sc with Urqmd cov- ering two highest collision energies. Hijing shows a concave behavior with extreme points matching the measurements. In order to compare the detailed features ...
