Investigation of the phase structure of a chirally-invariant Higgs-Yukawa model

TL;DR

This paper explores the phase structure of a chirally-invariant Higgs-Yukawa model at large Yukawa couplings, including finite temperature effects and hypothetical fourth-generation quarks, to understand its behavior under various conditions.

Contribution

It provides new extended data on the phase structure of the Higgs-Yukawa model, incorporating larger volumes, more Yukawa couplings, and finite temperature scenarios with both physical and hypothetical top quark masses.

Findings

Extended data on phase transitions at large Yukawa couplings.

Finite temperature effects at physical and hypothetical quark masses.

Insights into the model's behavior with increased volume and coupling diversity.

Abstract

We present new data on our ongoing project on the investigation of the phase structure of the Higgs-Yukawa model at large bare Yukawa couplings. The data presented last year are extended in terms of statistics, the number of bare Yukawa couplings at existing, and new larger volumes. In addition, this study is extended by a finite temperature project at the physical top quark mass m_t =175 GeV and a hypothetical fourth generation top quark with a mass of m_t' =700 GeV .
