B -> K* gamma vs B -> rho gamma and |Vtd/Vts|
Abstract
We determine |V td/V ts| = 0.192 0.016 exp 0.014th from B -> (K*,rho) gamma as measured by the B-factories Babar and Belle. This version differs from the original proceedings by the inclusion of the new BaBar measurement of B -> rho(omega) gamma presented at ICHEP 2006, which significantly shifts the results for |Vtd/Vts|.
