Summary

Preliminary results of an investigation of multiple pion production without annihilation in antiproton-proton collisions at 7 GeV/c exhibit highly peripheral characteristics. The experimental distributions in the reaction\(\bar p + p \to \bar p + p + \pi ^ + + \pi ^ - \) are consistent with a one-pion-exchange mechanism particularly for low four-momentum transfers. The cross-section for multipion production without annihilation is ∼20 mb.

Riassunto

Secondo i risultati preliminari di uno studio, la produzione multipla di pioni senza aanichilazione nelle collisioni antirptone-protone a 7 GeV/c presenta caratteristiche spiccatamente periferiche. Le distribuzioni sperimentali della reazione\(\bar p + p \to \bar p + p + \pi ^ + + \pi ^ - \) sono compatibili con un meccanismo di scambio di un pione, particolarmente a bassi quadrimomenti trasferiti. La sezione d’urto per la produzione multipla di pioni senza annichilazione è ∼ 20 mb.
