Summary
The possible contribution of a ρ-exchange process to the photoproduction of ρ-mesons, which subsequently decay to high-energy pions at very small angles, is examined when the ρ-nucleon vertex is replaced by the total cross-section for ρ-induced reactions.
Riassunto
Si esamina il possibile contributo di un processo di scambio di ρ alla fotoproduzione di mesoni ρ, che successivamente decadono in pioni di alta energia ad angoli molto piccoli, quando il vertice ρ-nucleone è sostituito con la sezione d’urto totale delle reazioni indotte dai ρ.
