Title: Measurement of the yields of positively charged particles at an angle of 35 Degree-Sign in proton interactions with nuclear targets at an energy of 50 GeV

Journal Article · · Physics of Atomic Nuclei

Momentum spectra of cumulative particles in the region of high transverse momenta (P{sub T}) in pA {yields} h{sup +} + X reactions were obtained for the first time. The experiment in which this was done was performed at the SPIN setup (Institute for High Energy Physics, Protvino) in a beam of 50-GeV protons interacting with C, Al, Cu, and W nuclei. Positively charged particles were detected at a laboratory angle of 35 Degree-Sign and in the transverse-momentum range between 0.6 and 3.7 GeV/c. A strong dependence of the particle-production cross section on the atomic number was observed. A comparison with the results of calculations based on the HIJING and UrQMD models was performed in the subcumulative region.
