Dynamical chiral symmetry breaking in strangelets at finite temperature

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.
