Tensor glueball photoproduction and decay

Abstract

Using vector meson dominance (VMD), tensor glueball photoproduction cross sections, asymmetries and widths are calculated. The predicted hadronic VV′ decays are comparable for different vector meson (V=ρ,ω and ϕ) channels with the ωϕ width the largest but the radiative ωγ and ϕγ decays are suppressed relative to ργ by over a factor of 2. This decay profile is distinct from typical meson branching rates and may be a useful glueball detection signature. Results are compared to a previous VMD scalar glueball study.
