Dimension-6 Operator Constraints from Boosted VBF Higgs
We discuss the constraints on new physics from Higgs production through vector boson fusion in the context of an eective eld theory that preserves Standard Model gauge symmetries. We nd that the constraints on dimension-6 operators are signicantly improved over those from the VBF signal strength by studying the Higgs transverse momentum distribution. Focusing on the OHW operator, we nd that boosted VBF decaying to photons yields constraints competitive with boosted WW production in the fully leptonic nal state, and calculate projected limits for both at the 14 TeV LHC. The pT cuts required to maximize the the reach of VBF searches are substantially softer, making the use of the eective eld theory more robust than in the case of WW production which requires very highpT cuts to obtain similar limits. Boosted VBF Higgs is thus an important probe of new physics.
