Proton Stripping and Pion Production in Relativistic Deuteron-Nucleus Collisions

We construct a Glauber theory for the proton stripping and the pion production in relativistic deuteron-nucleus collisions, taking into account the relativistic dilation of the internal deuteron wave function. The theory is applied to the experiments performed at the Bevalac with 1.05 and 2.1 GeV/nucl. incident deuterons. The observed broadening of the stripped proton spectrum is explained as coming from the relativistic dilation effect. The production of fast pions is described as initiated from nucleons of the incident deuteron, whose momenta are large, again due to the relativistic dilation. Both the momentum shapes and theΛ-dependence of the cross-sections for the different reactions are well reproduced.
