Summary
The formalism of Regge poles is applied to the process of single-pion production in π-N collisions at high energies. It is assumed that at these energies this process is dominated by Regge poles in the « crossed » channel, namely nucleon-antinucleon annihilation into three pions. By a slight generalization of the usual peripheral model, we calculate the asymptotic form of the cross-section. Some preliminary experimental consequences are also indicated.
Riassunto
Si applica il formalismo dei poli di Regge al processo di produzione di pioni singoli nelle collisioniπ-N di alta energia. Si suppone che a queste energie tale processo sia dominato da poli di Regge nel canale « incrociato », cioè dall’annichilazione nucleone-antinucleone in tre pioni. Con una lieve generalizzazione del solito modello periferico, si calcola la forma asintotica della sezione d’urto. Si indicano anche alcune conseguenze sperimentali preliminari.
