Consequences of a noncovariant description of slow and fast protons from p-C, C-C, and C-Ta interactions at 3.3A GeV -: art. no. 024901

A comparison is made between a typical intranuclear cascade (INC) model and the experimental inclusive slow (T<0.4 GeV) and fast (T>0.4 GeV) proton spectra in the p-C, C-C, and C-Ta in interactions at 3.3A GeV over a broad angular interval from 0degrees to 180degrees. It is found that the INC model reproduces rather well the inclusive slow and fast proton spectra, provided that the mean number of interacting protons (participants) in the corresponding angular interval does not exceed 2. The systematic discrepancies are identified and shown to correspond mainly to the noncovariant nature of the INC calculations.
