Pion Double Charge Exchange on Nuclei and Inelastic Rescatterings

Abstract

The inclusive pion double charge exchange process on nuclei is considered in the framework of the Gribov-Glauber approach. It is shown that inelastic rescatterings related to production of two (and more) pions in the intermediate state give an important contribution to the process of double charge exchange at kinetic energies above ~ 0.5 GeV. This mechanism dominates at energies greater or about 1 GeV and allows to explain the weak energy dependence of the double charge exchange cross section observed experimentally.
