Symmetry Restoration at High Temperature in Little Higgs Models?

TL;DR

This paper demonstrates that the previously believed non-restoration of symmetry at high temperatures in Little Higgs models is incorrect when thermal corrections are properly included, leading to symmetry restoration.

Contribution

It clarifies that symmetry non-restoration in Little Higgs models is not intrinsic, emphasizing the importance of thermal corrections in high-temperature behavior.

Findings

Thermal corrections lead to electroweak symmetry restoration in Little Higgs models.

Symmetry non-restoration is not an inherent feature of Little Higgs models.

Proper inclusion of thermal effects changes the high-temperature phase structure.

Abstract

In this work, we show that the apparent symmetry non-restoration at high temperature for Little Higgs (LH), is not intrinsic feature for LH. We show that when including such dominant thermal corrections, the EW symmetry gets restored.
