QCD radiative corrections to the leptonic decay rate of the Bc meson.
The QCD radiative corrections to the leptonic decay rate of the B c meson are calculated using the formalism of nonrelativistic QCD (NRQCD) to separate short-distance and long-distance effects. The B c decay constant is factored into a sum of NRQCD matrix elements each multiplied by a short-distance coefficient. The short-distance coefficient for the leading matrix element is calculated to orde...
متن کاملQCD CORRECTIONS TO THE RADIATIVE DECAY ¯B → Xsγ
In this short review, the calculation of the next-to-next-to-leading order QCD corrections to the inclusive radiative decay B̄ → Xsγ is described. I summarize the salient features of the calculational framework adopted, discuss the results obtained in the last few years, and indicate the technical tools that made the NNLO calculations possible. I conclude by comparing the current NNLO theoretica...
متن کاملResummation of QCD Corrections to the ηc Decay Rate
We examine the ratio of the decay rate of the ηc into light hadrons to the decay rate into photons and find that most of the large next-to-leading-order (NLO) correction is associated with running of the strong coupling αs. We resum such contributions by analyzing final-state chains of vacuum-polarization bubbles. We show that the nonperturbative parts of the bubble chains can be absorbed into ...
متن کاملQCD corrections to charged triple vector boson production with leptonic decay
We compute the O(αs) QCD corrections to charged triple vector boson production at a hadron collider, i.e. the processes pp → ZZW +X and pp → WWW +X. Intermediate Higgs boson exchange effects, spin correlations from leptonic vector boson decays, and off-shell contributions are all taken into account. Results are implemented in a fully flexible Monte Carlo program that allows for an easy customiz...
متن کاملQCD Corrections to Radiative Υ Decays
We have calculated the next-to-leading order perturbative QCD corrections to the photon energy spectrum in radiative Υ decays. The higher-order corrections significantly modify the shape of the spectrum, in particular at large photon energies, and thereby reduce the discrepancy between experimental data and previous leading-order predictions. The next-to-leading order calculation of the photon ...
