Abstract

Abstract : We present an analysis of proton and charged pion transverse momentum spectra of p + Cu and p + Pb reactions at 3, 8, and 15 GeV/ c in 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 both p + Cu and p + Pb collisions decrease with increasing the angle for the same incident momentum.
