I will give a brief introduction to the public software package GAMBIT (the Global and Modular Beyond-the-Standard-Model Inference Tool) and present the first SUSY results from the BSM science programme currently being pursued with it. We have performed global fit analyses of both GUT-scale and weak-scale parameterisations of the MSSM. Our analyses improve on existing results in terms of the...

Particle Phenomenology
In several supersymmetric (SUSY) models the Higgs mass is predicted to be smaller than the Z boson mass. Therefore, in order for a SUSY model to predict the correct Higgs mass of 125 GeV, large loop corrections are required. Such large loop corrections are achieved in scenarios with large stop masses and/or a large stop mixing. However, the large loop corrections lead to a slow convergence...

Massive neutrinos are required to explain the observation of neutrino oscillations. One of the simplest extension of the Standard Model that can successfully generate neutrino masses and mixing is the addition of fermionic gauge singlets or heavy sterile neutrinos. If an approximate lepton number symmetry is present, these sterile neutrinos can have a mass close to the TeV-scale with large...

The complex two-Higgs doublet model is one of the simplest ways to extend the scalar sector of the Standard Model to include a new source of CP-violation. This can address the matter antimatter asymmetry in the universe through electroweak baryogenesis and can also lead to interesting collider phenomenology.
Quantifying the amount of CP-violation, however, remains a surprisingly non-trivial...

The Higgs self-coupling is notoriously intangible at the LHC. It was recently proposed to probe the trilinear Higgs interaction through its radiative corrections to single-Higgs processes. This approach however requires to disentangle these effects from those associated to deviations of other Higgs-couplings to fermions and gauge bosons. We show that a global fit exploiting only single-Higgs...
