Higher-order QED corrections to W-boson mass determination at hadron colliders

The impact of higher-order final-state photonic corrections on the precise determination of the W-boson mass at the Tevatron and LHC colliders is evaluated. In the presence of realistic selection criteria, the shift in the W mass from a fit to the transverse mass distribution is found to be about

Multiple photon corrections to the neutral-current Drell-Yan process

Precision studies of single W and Z production processes at hadron colliders require progress in the calculation of electroweak radiative corrections. To this end, higher-order QED corrections to the neutral-current Drell-Yan process, due to multiple photon radiation in Z leptonic decays, are calculated. Particular attention is paid to the effects induced by such corrections on the experimental observables which are relevant for high-precision measurements of the W-boson mass at the Tevatron Run II and the LHC. The calculation is implemented in the Monte Carlo event generator HORACE, which is available for data analysis.

Multiple Photon Corrections to W and Z Boson Production at Hadron Colliders

The W and Z production processes play an important role in the physics program of hadron colliders. The expected accuracy at the Tevatron Run II and the LHC requires progress in the calculation of electroweak radiative corrections to these processes. To this end, higher order QED corrections to the Drell‐Yan‐like W and Z production, due to final state multiple photon radiation, are calculated. Particular attention is paid to the effects induced by such corrections on the experimental observables which are relevant for high precision measurements of the W boson mass. The calculation is implemented in the Monte Carlo event generator HORACE, which is available for data analysis.
