We investigate simplified models of dark matter with scalar mediators at hadron colliders using the final state topology with two jets and missing energy. These models can arise in a wide variety of BSM scenarios including the possibility of the medi... Read More about Spectroscopy of scalar mediators to dark matter at the LHC and at 100 TeV.

Diagrammatic computation of multi-Higgs processes at very high energies: scaling logσn with MadGraph (2015)
Journal Article

At very high energies scattering amplitudes in a spontaneously broken gauge theory into multiparticle final states are known to grow factorially with the number of particles produced. Using simple scalar field theory models with and without the vacuu... Read More about Diagrammatic computation of multi-Higgs processes at very high energies: scaling logσn with MadGraph.

Upper limit on the scale of new physics phenomena from rising cross sections in high multiplicity Higgs and vector boson events (2015)
Journal Article

In very high energy scattering events, production of multiple Higgs and electroweak gauge bosons becomes possible. Indeed the perturbative cross section for these processes grows with increasing energy, eventually violating perturbative unitarity. In...
