Forward particle production in proton–nucleus interactions at momenta of 25 and 50 GeV/с and сarbon–nucleus interactions at an energy of 25 GeV per nucleon

Abstract

Relative yields of high-x F charged hadrons (π ±, К±, р, $$\overline p $$ , and d) in proton–nucleus interactions at incident-proton momenta of 25 and 50 GeV/c were measured at an angle of 0° in the momentum range between 15 and 40 GeV/c. An upper limit on the forward production of two protons in proton–nucleus interactions at 50 GeV/c was estimated. The properties of a carbon beam with an energy of 25 GeV per nucleon and fragment yields in its interaction with nuclear targets were measured within a short exposure.
