Production of gamma (9.5) in E exp + E exp - Annihilation and Photoproduction

摘要

Assuming that the new resonance gamma (9.5) is a vector meson, its leptonic and hadronic decay widths are calculated in analogy to those of psi(3.1). Then, using the Breit-Wigner formula, the production cross section in e exp + e exp - annihilation is predicted. The tensor dominance of the Pomeron, together with the vector dominance model, is invoked to estimate the photoproduction cross section. (ERA citation 03:016136)
