Wγproduction in vector boson fusion at NLO in QCD

The next-to-leading order QCD corrections to ${W}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\gamma}$ production in association with two jets via vector boson fusion are calculated, including the leptonic decay of the $W$ with full off-shell effects and spin correlations. The process lends itself to a test of quartic gauge couplings. The next-to-leading order corrections reduce the scale uncertainty significantly and show a nontrivial phase space dependence.
