摘要：

The impact of higher-order final-state photonic corrections on the precise determination of the W-boson mass at the Fermilab Tevatron and CERN 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 10 MeV in the W-->munu channel and a few MeV in the W-->enu channel. The calculation, which is implemented in a Monte Carlo event generator for data analysis, can contribute to reduce the uncertainty associated with the W mass measurement at future hadron collider experiments.
