Quark model predictions for $K^{\ast }$ photoproduction on the proton

Abstract

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