Summary

The longitudinal and transverse parts of the πΔ(1236) electroproduction cross-section are predicted from real photoproduction within the framework of vector-meson dominance, using the assumption of approximate mass independence of the invariant amplitudes for VN→πΔ(1236).

Доминантность векторного меэона и гладкость инвариантных амплитуд в злектророждении πΔ(1236)

Реэюме

Испольэуя предположение о приближенной неэависимости от массы инвариантных амплитуд для VN→πΔ(1236), предскаэываются продольная и поперечная части поперечного сечения злектророждения πΔ(1236), исходя иэ реального фоторождения в рамках доминантности векторного меэона.

Riassunto

Si predicono le parti longitudinale c trasversale della sezione d’urto dell’elettroproduzione πΔ(1236) dalla fotoproduzione reale nel contesto del predominio del mesone vettoriale, facendo uso dell’ipotesi dell’approssimativa indipendenza dalla massa delle ampiezze invarianti per VN→πΔ(1236).

    The variation of the phase-space factora in eq. (27) withk 2 has been taken into account here in contrast to previous work (10) and results in a small ((10÷20)%) decrease of σU in comparison with ref. (10).CrossRefADSGoogle Scholar
