Production of cumulative particles and light nuclear fragments at high p T values beyond the fragmentation region of nuclei in pA collisions at a proton energy of 50 GeV

Abstract

The first data on the production of cumulative π+, p, and light nuclear fragments d and t emitted from a nucleus with a high transverse momentum at an angle of 35° in the laboratory system have been reported. The data have been obtained at the SPIN setup at the interaction of a 50-GeV proton beam extracted from the U-70 accelerator (IHEP, Protvino) with C, Al, Cu, and W nuclei.
