Abstract

The results of proton-proton and deuteron-deuteron scattering simulation at total collision energies √s = 6 and 10 GeV in the SPDRoot framework are presented. Based on the simulation of elastic and inelastic scattering processes, the possibility of selection of the pp- and dd-elastic scattering events using beam-beam counters is discussed. The results for the two well-known event generators, FRITIOFF and Pythia8, are compared. The simulation shows that the contribution of background events increases with increasing energy. For the maximum energy considered, the acceptable background level can be achieved only for the central rings.
