Electroweak corrections and shower effects to Higgs production in association with two jets at the LHC
Journal of High Energy Physics(2022)
摘要
bstract We present an implementation of the full electroweak H + 2 jets production process at hadron colliders in the framework of the POWHEG 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.
