$|V_{td}/V_{ts}|$ from $B\to V \gamma$

The dominant theoretical uncertainty in extracting |V_td/V_ts| from the ratio of branching ratios R=B(B->(rho,omega)gamma)/B(B-> K* gamma) is given by the ratio of form factors xi = T_1^{B->K*}(0)/T_1^{B-> \rho}(0). We re-examine xi in the framework of QCD sum rules on the light-cone, ta...
