A new BLHA interface between VBFNLO 3.0 and Herwig 7.3 enables NLO+PS matching for all di-boson and tri-boson leptonic processes, and a study of the W+W-γ process finds that generation-level cuts can shift predictions by up to 10%.
The EW parameters are set to the standard values used in Herwig 7.3: mW = 80.3770 GeV, ΓW = 2.085 GeV mZ = 91.1876 GeV, ΓZ = 2.495 GeV GF = 1.16637 · 10−5 GeV−2
