Neutron fragmentation in the reaction pn to pX at 19 GeV/c

Data on the reaction pn to pX are extracted from a pd experiment in the CERN 2 m DBC at 10 GeV/c. The cross-section for neutron fragmentation events with mod t mod <1 (GeV/c)/sup 2/ determined and compared with data at high energies at fixed M/sub x//sup 2//s and t.

description Data on the reaction pn to pX are extracted from a pd experiment in the CERN 2 m DBC at 10 GeV/c. The cross-section for neutron fragmentation events with mod t mod <1 (GeV/c)/sup 2/ determined and compared with data at high energies at fixed M/sub x//sup 2//s and t. The cross-section can be described with the triple-Regge formula taking into account only the pion exchange contributions, i.e. the pi pi P and pi pi R terms. A leading-particle effect consistent with the pion exchange model is observed in the longitudinal-momentum distribution of the negative pions in the final state of the reaction pn to pX, when transformed to the rest frame of the recoiling system X. (10 refs).
