# Electroweak Phase Transitions in Einstein's Static Universe

## TL;DR

This paper proposes using Einstein's static universe metric to model the metastable state after reheating, showing that strong static gravity can facilitate a first-order electroweak phase transition and enhance baryogenesis.

## Contribution

It introduces a novel approach of applying Einstein's static universe metric to electroweak phase transition modeling, highlighting gravity's role in baryogenesis.

## Key findings

- Static gravitational potential reduces Higgs VEV compatible with first-order transition.
- Gravity enhances CP-violating effects at phase bubble walls.
- Model supports electroweak baryogenesis within Standard Model conditions.

## Abstract

We suggest using Einstein's static universe metric for the metastable state after reheating, instead of the Friedman-Robertson-Walker spacetime. In this case strong static gravitational potential leads to the effective reduction of the Higgs vacuum expectation value, which is found to be compatible with the Standard Model first order electroweak phase transition conditions. Gravity could also increase the CP-violating effects for particles that cross the new phase bubble walls and thus is able to lead to the successful electroweak baryogenesis scenario.
