Radiative corrections in weak semi-leptonic processes at low energy: a two-step matching determination
We focus on the chiral Lagrangian couplings describing radiative corrections to weak semi-leptonic decays and relate them to the decay amplitude of a lepton, computed by Braaten and Li at one loop in the Standard Model. For this purpose, we follow a two-step procedure. A first matching, from the Standard Model to Fermi theory, yields a relevant set of counterterms. The latter are related to chi...
متن کاملRadiative Corrections in Processes at the Ssc *
We discuss radiative corrections for interactions in the SSC environment. Based on the theory of Yennie, Frautschi and Suura, we develop appropriate Monte Carlo event generators to compute the background electromagnetic radiation. Our results indicate that multiple-photon effects must be taken into account in the study of SSC physics such as Higgs decay. Supported in part by the Texas National ...
متن کاملRadiative corrections to low-energy neutrino reactions
We show that the radiative corrections to charged current ~CC! nuclear reactions with an electron ~positron! in the final state are described by a universal function. The consistency of our treatment of the radiative corrections with the procedure used to extract the value of the axial coupling constant gA is discussed. To illustrate we apply our results to ~anti! neutrino deuterium disintegrat...
متن کاملElectroweak Radiative Corrections to Weak Boson Production at Hadron Colliders
We summarize the status of calculations of the electroweak radiative corrections to W and Z boson production via the Drell-Yan mechanism at hadron colliders. To fully exploit the precision physics potential of the highluminosity environment of the Fermilab Tevatron pp̄ (Run II) and the CERN LHC pp colliders, it is crucial that the theoretical predictions are well under control. The envisioned pr...
متن کاملRadiative Corrections to Low-Energy Neutrino-Deuteron Reactions Revisited
The one-loop QED and electroweak radiative corrections to neutrino-deuteron scattering induced by the neutral current are reexamined, paying a particular attention to the constant term which has never been treated properly in literature. This problem is closely related to the definition of the axial-vector coupling constant gA and requires thorough calculations of the constant terms in the char...
