Vacuum stability from vector dark matter
Presented by Mr. Mateusz DUCH
We study a model of a vector dark matter coming from the complex scalar Higgs portal with an additional U(1) gauge symmetry. Renormalisation group equations at the 2-loop level are used to analyse perturbativity and influence of the dark gauge coupling on the vacuum stability. We discuss LHC and LEP constraints on the additional Higgs-like scalar present in the model and bounds coming from the Planck data and direct detection experiments.
