Production ofϒ(9.5)ine+e−Annihilation and Photoproduction

Abstract

On the assumption that the new resonance $\Upsilon \mathrm{}\left(9.5\right)\mathrm{}$ is a vector meson, its leptonic- and hadronic-decay widths are calculated in analogy to those of $\psi \mathrm{}\left(3.1\right)\mathrm{}$. Then, using the Breit-Wigner formula, the production cross section in $e^{+}{e}^{-}$ annihilation is predicted. The tensor dominance of the Pomeron, together with the vector-dominance model, is invoked to estimate the photoproduction cross section.
