Study of the Leutwyler-Smilga regimes: Lessons for full QCD simulations

Abstract

Some key points out of my recent study of the characteristic features of the small ($x\ll 1$), intermediate ($x\simeq 1$) and large ($x\gg 1$) Leutwyler-Smilga regimes for QCD-type theories in a finite volume ($x=V\Sigma m$) are presented, and a few immediate consequences for full QCD simulations are discussed.
