Abstract: We have given an explanation for the pseudorapidity distribution of charged particles produced in $d+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\phantom{\rule{0.3em}{0ex}}\mathrm{GeV}$ [the maximum relativistic heavy ion collider (RHIC) energy]. A simple cylinder model is used in this paper which contains four components: leading projectile protons, leading target protons, cascade collisions in the gold spectator, and a cylinder. The model gives a good description for the experimental data obtained with the PHOBOS detector at RHIC. The high stage and high peak in the gold fragmentation region of the pseudorapidity distribution are contributed by the leading gold protons and the cascade collisions in the gold spectator, respectively.
