多费米自由度类QCD理论的晶格研究

Lattice studies of QCD-like theories with many fermionic degrees of freedom

Thomas DeGrand

摘要:

我给一个初步的介绍规范理论的研究耦合到费米子与多个自由度。除了它们的内在兴趣,这些理论是标准模型的希格斯扇区的非微扰扩展的候选者。虽然与QCD有关,但这些系统可以表现出与QCD非常不同的行为:它们可以拥有与红外吸引固定点(IRFP)耦合的运行规范。我简要地调查最近在这方面的晶格工作。

英文摘要:

I give an elementary introduction to the study of gauge theories coupled to fermions with many degrees of freedom. Besides their intrinsic interest, these theories are candidates for nonperturbative extensions of the Higgs sector of the Standard Model. While related to QCD, these systems can exhibit very different behavior from it: they can possess a running gauge coupling with an infrared attractive fixed point (IRFP). I briefly survey recent lattice work in this area.
