Description

The decay W- → jet+jet+γ is studied using the Lund string fragmentation scheme and including O(αs) leading QCD corrections. Even with fragmentation and full parton showers included, the radiation amplitude zero characteristic of the fundamental Yang-Mills WWγ coupling leaves a clear signal in the W center-of-mass frame.
