Title: On the fragmentation of relativistic deuterons on nuclei

Abstract

The contributions of different fragmentation mechanisms of relativistic deuterons into protons on nuclei are studied. It is shown that in order to describe the entire proton momentum spectrum, processes involving the creation of intermediate ..pi..-mesons with subsequent absorption or rescattering by a spectator nucleon must be taken into account, in addition to stripping processes, which give the dominant contribution. The former process dominates in a certain kinematic region. A possible admixture of the six-quark state to the deuteron wave function contributes only in the high-momentum region of the proton spectrum, where the contributions of other mechanisms become unimportant.
