Dynamical chiral symmetry breaking in strangelets at finite temperature

TL;DR

This paper models strangelets at finite temperature, showing that chiral symmetry spontaneously breaks inside them at certain temperatures, leading to increased strange quark masses as temperature rises.

Contribution

It introduces a model for strangelets with dynamically generated quark masses and investigates chiral symmetry breaking at finite temperature.

Findings

Chiral symmetry spontaneously breaks inside strangelets at finite temperature.

Strange quark masses increase with temperature after symmetry breaking.

Numerical examples illustrate the mass-temperature relationship.

Abstract

A model for strangelets at finite temperature is built, in which the quark masses are dynamically generated. The dynamical chiral symmetry breaking inside strangelets at finite temperature is investigated. It is found that the chiral symmetry is going to break spontaneously inside the strangelets at some finite temperature, and then the masses of strange quarks inside the strangelets increase as the temperature rises. The phenomenon that strange quark mass increases with temperature after the chiral symmetry breaks spontaneously is illustrated by some typical numerical examples.
