Nonfactorizable QCD and Electroweak Corrections to the Hadronic Z Boson Decay Rate.
We present an analysis of two-loop mixed QCD and electroweak corrections to the decay of the Z boson into light quarks. We find that the naive factorization of QCD and electroweak corrections does not describe correctly the two-loop effects. The nonfactorizable corrections shift the width of the Z boson by approximately −0.59(3) MeV and increase the central value of the strong coupling constant...
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 کاملElectroweak corrections to the toponium decay width
We discuss one-loop electroweak corrections to the decay width of toponium. We calculate the energy-level shifts by expanding around the solution of the Bethe-Salpeter equation in the instantaneous approximation, in analogy with the positronium case. We show that first-order electroweak effects are suppressed by at least four powers of the strong coupling constant, and are therefore negligible ...
متن کاملElectroweak Corrections to the Top Quark Decay
We have calculated the one-loop electroweak corrections to the decay t→ bW, including the counterterm for the CKM matrix elements Vtb. Previous calculations used an incorrect δVtb that led to a gauge dependent amplitude. However, since the contribution stemming from δVtb is small, those calculations only underestimate the width by roughly one part in 10. PACS number(s): 12.15.Lk, 11.10.Gh, 12.1...
متن کاملElectroweak & QCD corrections to Drell Yan processes
The relevance of single-W and single-Z production processes at hadron colliders is well known: in the present paper the status of theoretical calculations of Drell-Yan processes is summarized and some results on the combination of electroweak and QCD corrections to a sample of observ-ables of the process pp → W ± → µ ± + X at the LHC are discussed. The phenomenological analysis shows that a hig...
