Measurement of branching fractions, isospin and CP-violating asymmetries for exclusive \boldmath$b\to d\gamma$ modes

N. Taniguchi, M. Nakao, S. Nishida

We report new measurements of the decays $B\to {\rho }^{+}\gamma$, $B\to {\rho }^0\gamma$ and $B\to \omega \gamma$ using a data sample of $657\times 10^6$ $B$ meson pairs accumulated with the Belle detector at t…
