Abstract
The diffractive dissociation of pions into 3π and 5π final states has been studied using π− d interactions at 15 GeV/c. Peripherally produced low-mass enhancements are observed in both channels. the 3π enhancements consist predominantly of two-body final states, ϱπ, andfπ; evidence for agπ enhancement is inconclusive. The 5π channel shows no strong two-body structure. A multiperipheral Deck model and the statistical dissociation model are studied as possible mechanisms for these enhandements. The multiperipheral model describes the 3π channel well, whereas the less structured statistical model gives a better description of the 5π data.
