Electroweak corrections and shower effects to Higgs production in association with two jets at the LHC

Abstract

We present an implementation of the full electroweak $H+2\text{jets}$ production process at hadron colliders in the framework of the $\mathtt{POWHEG}\mathtt{BOX}$, a public tool for the matching of fixed-order perturbative calculations with parton shower generators. Our implementation allows for the simultaneous description of vector-boson fusion and Higgsstrahlung contributions. NLO-QCD and electroweak corrections are taken into account and matched to QCD and QED showers, respectively. The size of the fixed-order QCD and electroweak corrections is found to be moderate, but dependent on the considered selection cuts. QCD shower effects slightly modify the NLO-QCD predictions and are most pronounced for distributions of non-tagging jets. The impact of QED shower effects is small.
