NLO multijet merging for Higgs production beyond the VBF approximation

Abstract

Abstract We present results of the simulation of electroweak Higgs boson production at the Large Hadron Collider using both the NLO multijet merging and NLO matching frameworks provided by the general purpose event generator Herwig 7. For the simulation of the hard scattering processes, we use the HJets library for the full calculation and VBFNLO for the approximate calculation to compute the $$2\rightarrow h+n$$ 2 → h + n amplitudes at tree-level with $$n=2,3,4$$ n = 2 , 3 , 4 and at one-loop with $$n=2,3$$ n = 2 , 3 .
