Symmetry Nonrestoration in the Pati-Salam Model
N. Okada, A. Stern
TL;DR
This paper shows that in the Pati-Salam model, symmetry can remain broken at high temperatures, preventing monopole formation and relaxing constraints on the symmetry breaking scale.
Contribution
It introduces finite-temperature effects and quartic couplings that prevent symmetry restoration in the Pati-Salam model, a novel mechanism for monopole avoidance.
Findings
Symmetry remains broken at high temperatures in the Pati-Salam model.
Thermal monopole production can be avoided with suitable couplings.
Constraints on the symmetry breaking scale are relaxed.
Abstract
We demonstrate that symmetry need not be restored in the Pati-Salam model, so that remains broken to the Standard Model group at temperatures above the Pati-Salam symmetry breaking scale. Including the leading finite-temperature corrections, suitable quartic couplings prevent a restoration transition, thereby avoiding the thermal production of 't Hooft-Polyakov monopoles after inflation, even if the reheating temperature is very high. This removes monopole-based constraints on the Pati-Salam symmetry breaking scale.
