In this White Paper we present and discuss a concrete proposal for the consistent interpretation of Dark Matter searches at colliders and in direct detection experiments. Based on a specific implementation of simplified models of vector and axial-vec...

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...

We outline and investigate a set of benchmark simplified models with the aim of providing a minimal simple framework for an interpretation of the existing and forthcoming searches of dark matter particles at the LHC. The simplified models we consider... Read More about Constraining Dark Sectors at Colliders: Beyond the Effective Theory Approach.

Using the classical recursion relations we compute scattering amplitudes in a spontaneously broken Gauge-Higgs theory into final states involving high multiplicities of massive vector bosons and Higgs bosons. These amplitudes are computed in the kine... Read More about Perturbative growth of high-multiplicity W, Z and Higgs production processes at high energies.
