NNLL Electroweak Corrections to Gauge Boson Pair Production at LHC
The high energy behaviour of electroweak corrections to gauge boson pair production at LHC can be derived in the framework of evolution equations up to NNLL contributions to all order in perturbation theory. On the basis of this general result we derive the one-and two-loop cross section in NNLL approximation for W-pair production at partonic and hadronic level. c Copyright owned by the author(...
متن کاملQCD Corrections to Double and Single Spin Asymmetries in Vector Boson Production at Polarized Hadron Colliders
The production of W and Z0 bosons in collisions of longitudinally polarized protons allows to access various combinations of the polarized quark distributions from the study of double and single spin asymmetries. We compute the O(αs) corrections to these asymmetries as function of the vector boson rapidity y in the hadron–hadron centre-of-mass frame. Detailed studies of the numerical impact of ...
متن کاملRadiative corrections to off-shell gauge-boson pair production
In recent years we have grown increasingly accustomed to the great success of the Standard Model (SM) of electroweak interactions. However, up to now only a relatively restricted sector of the SM has been checked. The Yang–Mills character of the gauge-boson self-interactions and the Higgs mechanism of mass generation still await conclusive confirmation. This leaves ample of room for interesting...
متن کاملElectroweak Radiative Corrections to Resonant Charged Gauge Boson Production
The electroweak O(α) contribution to the resonant single W production in a general 4-fermion process is discussed with particular emphasis on a gauge invariant decomposition into a QED-like and weak part. The cross section in the vicinity of the resonance can be represented in terms of a convolution of a ‘hard’ Breit-Wigner-cross section, comprising the (mt,MH)-dependent weak 1-loop corrections...
متن کاملUsing SCET to calculate electroweak corrections in gauge boson production
We extend an effective theory framework developped in Refs. [1, 2] to sum electroweak Su-dakov logarithms in high energy processes to also include massive gauge bosons in the final state. The calculations require an additional regulator on top of dimensional regularization to tame the collinear singularities. We propose to use the ∆ regulator, which respects soft-collinear factoriza-tion.
