Description

Minimal dark matter with a fermionic electroweak quintuplet is a phenomenologically valid dark matter model. I will discuss constraints coming from the renormalisation of this theory, namely vacuum stability, the location of the Landau pole, and the intra-multiplet mass splittings. In particular, I will demonstrate some subtleties and pitfalls in the phenomenologically crucial problem of calculating the mass splittings via a typical iterative pole mass calculation, as is standard in spectrum generator routines. This problem has implications for Wino-like dark matter and any electroweak extension of the standard model in which intra-multiplet mass splittings are an essential part of the theory.
