Rescattering in the nucleus forπ−dinteractions at 15 GeV/c

Abstract

We present the ${\pi }^{-}d$ charged multiplicity distributions at 15 GeV/c and examine the probability that the products of a ${\pi }^{-}n$ collision in a deuterium nucleus rescatter on the proton. Averaged over all topologies, this probability is 0.13±0.02. The rescatter probability as a function of the number of charged particles produced in the ${\pi }^{-}n$ interaction exhibits an increase at high multiplicity.
