Electroweak vacuum decay in metric-affine gravity
Ioannis D. Gialamas, Hardi Veermäe
Abstract
We investigate the stability of the electroweak vacuum in metric-affine gravity in which the Standard Model Higgs boson can be non-minimally coupled to both the Ricci scalar and the Holst invariant. We find that vacuum stability is improved in this framework across a wide range of model parameters.
