We consider partially quenched, mixed chiral perturbation theory with staggered sea and Ginsparg–Wilson valence quarks in order to extract a chiral-continuum extrapolation expression for the vector meson mass up to order {\mathcal O}(a^2) , at one-loop level. Based on general principles, we accomplish the task without explicitly constructing a sophisticated, heavy vector meson chiral Lagrangian.
