热杨-米尔斯理论中的准粒子和$Z(N)-$线
Quasiparticles and $Z(N)-$ lines in Hot Yang-Mills theories
摘要:
在这次演讲中,我们回顾了热杨-米尔斯理论的准粒子描述,其中准粒子在与Z(N)线相关的背景场中传播(并与之相互作用)。我们比较本说明与一个更常见的Z(N)线的影响被忽略。我们表明,它是可能的,即使没有发散的准粒子质量考虑到非微扰效应的限制转变温度。
英文摘要:
In this talk we review, the quasiparticle description of the hot Yang-Mills theories, in which the quasiparticles propagate in (and interact with) a background field related to Z(N)-lines. We compare the present description with a more common one in which the effects of the Z(N)-lines are neglected. We show that it is possible to take into account the nonperturbative effects at the confinement transition temperature even without a divergent quasiparticle mass.
