The magnetic field was scaled in proportion to the beam momentum in order to obtain similar y − pT accep- tance at all beam momenta. The main TPCs (MTPC-L/R) and two walls of pixel time-of-flight (ToF-L/R) detectors are placed symmetrically on either side of the beamline down-...
For the calculation, statistical uncertainties from the model with similar statistics to the data were used. Examples of such comparison are presented in Fig. 13. Fig. 13 Examples of comparison of results for two Power-law Model data sets with the experimental data. The left panel includes ...
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 ...
We also find that the spectra of π± are well described in the Angantyr approach for both models at different SPS energies. Other models have also been used to study pT spectra at midrapidity and rapidity spectra of π± and protons in the 20% most central 7Be + 9Be collisions at SPS...
