A measurement of the cross section of the reaction $pp \rightarrow n\Delta^{++} (1232)$ at ISR energies

A measurement of the cross section of the charge-exchange reaction pp to Delta /sup ++/(1232)n at square root s=23, 31 and 45 GeV at the CERN-ISR is reported. The energy dependences continues to follow a power law p/sub lab//sup -n/ with n=1.94+or-0.03 indicating dominance of one-pion exchange at th...

Descripción
Sumario:A measurement of the cross section of the charge-exchange reaction pp to Delta /sup ++/(1232)n at square root s=23, 31 and 45 GeV at the CERN-ISR is reported. The energy dependences continues to follow a power law p/sub lab//sup -n/ with n=1.94+or-0.03 indicating dominance of one-pion exchange at the lowest ISR energy; there is some evidence for deviation from this at the higher ISR energies.
