论文摘要
最近，有提案来理解QCD的特征，例如限制和手性对称性破坏，通过考虑具有各种软性破坏模式的理论的超对称版本。在本说明中，我们回想起，Susy QCD较小，暗示了实际QCD的特征。但是，我们概述了建立理论的这些特征的一些挑战。似乎很难争论限制或手性对称性。充其量，可以说{\ it if}非苏匹配理论不限制和/或打破手性对称性，随着一个人增加软性突破，相位过渡似乎是不可避免的。我们还讨论了大个子的限制，即限制意味着触手对称性的破坏，这是建立监禁的挑战。
Recently there have been proposals to understand features of QCD such as confinement and chiral symmetry breaking by considering supersymmetric versions of the theory with various patterns of soft breaking. In this note we recall that with small soft breakings, SUSY QCD is suggestive of observed features of real QCD. But we outline some of the challenges to establishing these features of the theory with large soft breakings. It appears difficult to argue for confinement or chiral symmetry breaking; at best, one can say that {\it if} the non-supersymmetric theory does not confine and/or break chiral symmetry, phase transitions would appear inevitable as one increases the soft breakings. We also discuss, at large N, where confinement would imply chiral symmetry breaking, the challenges to establishing confinement.
