Minimal dark matter and vacuum stability in global fits
James McKay, Imperial College London
I will discuss constraints from renormalisation of minimal dark matter including vacuum stability, perturbitivity and mass splittings. In particular I will explain challenges with the numerical calculation of electroweak mass splittings obtained from an iterative pole mass calculation, as is standard in spectrum generator routines. Finally I will introduce the global fitting tool GAMBIT with an explicit example of how a vacuum stability likelihood is implemented in this program.
