Abstract:Multiple pion production by pions in hydrogen has been studied in the interaction iT+p -> p+7r~+7r + +7r~" at 810, 970, and 1100 Mev. Total cross sections were measured as 0.26±0.14 mb at 810 Mev, 0.32d=0.21 mb at 970 Mev, and 0.54±0.32 mb at 1100 Mev. The kinematics of this pion production reaction at these energies appear to be reasonably well described by phase space dependence, but provide some support for an "isobar cascade" scheme in which the T = J "second resonance" is excited and decays to the T=J r =… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
