Emission of Protons and Charged Pions inp+ Cu andp+ Pb Collisions at 3, 8, and 15 GeV/c

Abstract

We present an analysis of proton and charged pion transverse momentum spectra ofp+Cuandp+Pbreactions at 3, 8, and 15 GeV/cin the framework of a multisource thermal model. The spectra are compared closely with the experimental data of HARP-CDP at all angular intervals. The result shows that the widths of the particle distributions in bothp+Cuandp+Pbcollisions decrease with increasing the angle for the same incident momentum.

Production of hydrogen isotopes and charged pions in p (3.5 GeV) + Nb reactions

“…Data provided by PISA cover a broad range of target nuclei (from C to Au) bombarded by protons of 1.2, 1.9 and 2.5 GeV energy [32,33,36,37,62,63]. The HARP-CDP collaboration provided proton and pion spectra for proton induced reactions on some atomic nuclei from Be to Pb at 4.1 GeV proton bombarding energy [39,[57][58][59][60][64][65][66][67].…”
