Bremsstrahlung Corrections to the Decay B ! Ss
نویسنده
چکیده
We calculate the O(s) gluon Bremsstrahlung corrections to the inclusive decay b ! ss, involving the full operator basis ^ O 1 { ^ O 8. Connrming and extending earlier calculations of Ali and Greub, we give formulas for the total decay width as well as the perturbative photon spectrum, regarding the former as a necessary part of the forthcoming complete NLO analysis. We explore in detail the renormalization scale dependence of our results and nd it considerably increased.

متن کاملQCD Corrections to the Decay B → X s l + l −
We briefly discuss the status of the NNLL QCD calculations in the inclusive rare B decay B → Xsll. Two important ingredients, the two-loop matrix elements of the four quark operator O2 and the bremsstrahlung contributions, were quite recently finalised. The new contributions significantly improve the sensitivity of the inclusive decay B → Xsll decay in testing extensions of the standard model i...
متن کاملHadron spectra for semileptonic heavy quark decay.
We calculate the leading perturbative and power corrections to the hadronic invariant mass and energy spectra in semileptonic heavy hadron decays. We apply our results to the B system. Moments of the invariant mass spectrum, which vanish in the parton model, probe gluon bremsstrahlung and nonperturbative effects. Combining our results with recent data on B meson branching ratios, we obtain a lo...

We calculate the virtual and bremsstrahlung fermionic corrections due to the interference of the electroand chromomagnetic dipole operators in the inclusive B̄ → Xsγ decay at O(αs) and present analytical results for both the total decay rate and the photon energy spectrum.
متن کاملThe Rare Decay B → Sg beyond Leading Logarithms *
We calculate the O(αs) virtual corrections to the decay width for b → sg in the standard model (g denotes a gluon). Also the corresponding O(αs) bremsstrahlung corrections to b → sg are systematically calculated in this paper. The combined result is free of infrared and collinear singularities, in accordance with the KLN theorem. Taking into account the existing next-toleading logarithmic (NLL)...
