Quark model predictions forK*photoproduction on the proton

Abstract

The photoproduction of ${K}^{*}$ vector mesons is investigated in a quark model with an effective Lagrangian. Including both baryon resonance excitations and t-channel exchanges, observables for the reactions $\ensuremath{\gamma}\stackrel{\ensuremath{\rightarrow}}{p}{K}^{*0}{\ensuremath{\Sigma}}^{+}$ and $\ensuremath{\gamma}\stackrel{\ensuremath{\rightarrow}}{p}{K}^{*+}{\ensuremath{\Sigma}}^{0}$ are predicted, using the SU(3)-flavor-blind assumption of nonperturbative QCD.
