| 英文摘要 | We report new measurements of the decays B+-> rho(+)gamma, B-0 -> rho(0)gamma, and B-0 -> omega gamma using a data sample of 657 x 10(6) B meson pairs accumulated with the Belle detector at the KEKB e(+) e(-) collider. We measure branching fractions B(B+ -> rho(+)gamma) = (8.7(-2.7-1.1)(+2.9+0.9)) x 10(-7), B(B-0 -> rho(0)gamma) = (7.8(-1.6-1.0)(+1.7+0.9)) x 10(-7), and B(B-0 -> omega gamma) = (4.0(-1.7)(+1.9)+/- 1.3) x 10(-7). We also report the isospin asymmetry Delta(rho gamma) = -0.48(-0.19-0.09)(+0.21+0.08) and the first measurement of the direct CP-violating asymmetry A(CP)(B+ -> rho(+)gamma) = -0.11 +/- 0.32 +/- 0.09, where the first and second errors are statistical and systematic, respectively. |
