Abstract

First-order phase transitions in the early universe might produce a detectable background ofgravitational waves. As these phase transitions can be generated by new physics, it is importantto quantify these effects. Many pure Yang-Mills gauge theories are known to undergo first-orderdeconfinement pha...
