Double inelastic charge exchange in interactions of 50-GeV/c π- mesons with nucleons and with light (CNO) and heavy (AgBr) emulsion nuclei; comparison with the constituent quark model
Experimental data are reported on double inelastic charge exchange, defined as the ratio of (a) the number of events in which the secondary particle having the maximum momentum has a charge sign differing by two from that of the incident particle to (b) the number of events in which the secondary particle with the maximum momentum has the same charge sign as the incident particle. The results found for the interaction of 50-GeV/c ir~ mesons with nucleons, light emulsion nuclei (CNO), and heavy emulsion nuclei (AgBr) are compared with calculations from the constituent-quark model. There is a satisfactory agreement.
