Simulation of Higgs boson pair production in Vector Boson Fusion at the LHC

MadGraph5 is used to generate events with Higgs boson pairs from vector boson fusion (VBF) at leading-order (LO) and next-to-leading-order (NLO) accuracy in QCD. The simulations are used to compute fiducial cross-sections in proton-proton collisions at a centre-of-mass energy of 13 TeV, using several kinematic cuts on the outgoing jets, e.g. the jet transverse momenta and pseudorapidity. The resulting cross-sections for NLO and LO are compared and their ratio,  the K-factor, is calculated for every kinematic cut. An attempt is made to extend the NLO simulation for non-Standard Model (SM) couplings between two vector bosons and two Higgs bosons (VVHH), however the corresponding model was found to be only compatible with LO accuracy in QCD.
