Query: $B \to \rho \gamma$ Decay in the Large Energy Effective Theory   The branching ratio for the $B \to \rho \gamma$ decay in the next-to-leading
order (NLO) in the strong coupling $\alpha_s$ and in leading power in
$\Lambda_{\rm QCD}/m_B$ is presented. The corrections are combined the
hard-vertex, hard-spectator and annihilation contributions and found to be
large. The theoretical expectation for the branching ratios, the
isospin-violating ratio and for the direct CP-asymmetry in the $B \to \rho
\gamma$ decays are presented.
