# Electroweak vacuum stability and the Higgs field relaxation via gravitational effects

@article{Torabian2020ElectroweakVS, title={Electroweak vacuum stability and the Higgs field relaxation via gravitational effects}, author={Mahdi Torabian}, journal={Classical and Quantum Gravity}, year={2020}, volume={37} }

The measured values of the standard model parameters favors a shallow metastable electroweak vacuum and a deep global minimum. The Higgs relaxation in its present local minimum can only be explained via a large degree of fine-tuning. In this paper, irrespective of new physics beyond the SM, we study the universal effect of gravity on the Higgs dynamics in the early universe. We consider a two-parameter framework in which the Higgs is non-minimally coupled to a higher-curvature gravity. In the…

Using a "thin-wall" approximation, a proof of principle is provided that small black holes can act as seeds for vacuum decay, spontaneously nucleating a new Higgs phase centered on the black hole with a lifetime measured in millions of Planck times rather than billions of years.

It is found that the stability of the electroweak (EW) vacuum strongly depends on new physics interaction at the Planck scale MP, despite of the fact that they are higher-dimensional interactions, apparently suppressed by inverse powers of MP.
