Electroweak radiative corrections to b → sγ
Two loop electroweak corrections to b → sγ decays are computed. Fermion and photonic loop effects are found to reduce R ≡ B(b → sγ)/B(b → ceν) by ∼ 8 ± 2% and lead to the standard model prediction B(B → Xsγ) = 3.28 ± 0.30 × 10 for inclusive B meson decays. Comparison of R = 3.04± 0.25× 10(1+0.10ρ), where ρ is a Wolfenstein CKM parameter, with the current experimental average R = 2.52±0.52×10−3 ...
متن کاملElectroweak Radiative Corrections to W Boson Production in Hadronic Collisions
The O(α) electroweak radiative corrections to the process p p (−) →W± → `±ν (` = e, μ) are calculated. The O(α) corrections can be decomposed into separately gauge invariant contributions to the W boson production and decay processes. Factorizing the collinear singularity associated with initial state photon radiation into the parton distribution functions, we find that initial state correction...
متن کاملElectroweak radiative corrections to W-boson production at hadron colliders
The complete set of electroweak O(α) corrections to the Drell–Yan-like production of W bosons is calculated and compared to an approximation provided by the leading term of an expansion about the W-resonance pole. All relevant formulae are listed explicitly, and particular attention is paid to issues of gauge invariance and the instability of the W bosons. A detailed discussion of numerical res...
متن کاملElectroweak Radiative Corrections to W Boson Production in Hadronic
The O(α) electroweak radiative corrections to the process p p (ℓ = e, µ) are calculated. The O(α) corrections can be decomposed into separately gauge invariant contributions to the W boson production and decay processes. Factorizing the collinear singularity associated with initial state photon radiation into the parton distribution functions, we find that initial state corrections have a signi...
متن کاملElectroweak Radiative Corrections to W Boson Production at the Tevatron
We discuss the O(α) electroweak radiative corrections to W boson production at the Tevatron and their effect on the W boson mass extracted by experiment. The results of a new calculation of the O(α) corrections are presented and compared with those of a previous calculation. We also briefly discuss the O(α) corrections to Z boson production at the Tevatron and two-photon radiation in W and Z ev...
