On Symmetry Non-Restoration at High Temperature

TL;DR

This paper investigates how higher-order quantum corrections influence the phenomenon where certain symmetries remain broken at high temperatures in a specific multi-symmetry model.

Contribution

It introduces the analysis of next-to-leading order effects on symmetry non-restoration in an $O(N_1) imes O(N_2)$ model, extending previous leading-order studies.

Findings

Next-to-leading order contributions significantly affect symmetry behavior at high temperatures.

The study clarifies conditions under which symmetry non-restoration persists.

Results provide deeper understanding of phase transitions in multi-symmetry models.

Abstract

We study the effect of next-to-leading order contributions on the phenomenon of symmetry non-restoration at high temperature in an $O(N_1)\times O(N_2)$ model.
