• W3101258024 abstract "Using results on soft-collinear factorization for inclusive B-meson decay distributions, a systematic study of the partial $Bto X_sgamma$ decay rate with a cut $E_gammage E_0$ on photon energy is performed. For values of E 0 below about 1.9 GeV, the rate can be calculated without reference to shape functions using a multi-scale operator product expansion (MSOPE). The transition from the shape-function region to the MSOPE region is studied analytically. The resulting prediction for the $Bto X_sgamma$ branching ratio depends on three large scales: m b , $sqrt{m_bDelta}$ , and $Delta = m_b-2E_0$ . Logarithms associated with these scales are resummed at next-to-next-to-leading logarithmic order. While power corrections in $Lambda_{mathrm {QCD}}/Delta$ turn out to be small, the sensitivity to the scale $Deltaapprox 1.1$ GeV (for $E_0approx 1.8$ GeV) introduces significant perturbative uncertainties, which so far have been ignored. The new theoretical prediction for the $Bto X_sgamma$ branching ratio with $E_gammage 1.8$ GeV is $mbox{Br}(Bto X_sgamma) = smash{(3.38_{ -0.42}^{ + 0.31}pm 0.31)}times 10^{-4}$ , where the first error is an estimate of perturbative uncertainties and the second one reflects uncertainties in input parameters. With this cut $smash{(89_{ -7}^{ + 6} pm 1)}%$ of all events are contained. When this fraction is combined with the previously best prediction for the total decay rate, one obtains $mbox{Br}(Bto X_sgamma) = (3.30_{ -0.35}^{ + 0.31}pm 0.17)times 10^{-4}$ , with a somewhat less conservative estimate of parametric uncertainties. The implications of larger theory uncertainties for new physics searches are briefly explored with the example of the type-II two-Higgs-doublet model, for which the lower bound on the charged-Higgs mass is reduced compared with previous estimates to approximately 200 GeV at 95% confidence level." @default.
