有效拉氏量理论

按照现代场论观点,所有现在所用的描述现实相互作用的理论都是某种更基本的理论的有效理论,有效理论的一个主要特点是其相互作用项一般是无穷多项.它与通常的可重整场论有很大差别.这里主要讨论一类特殊的有效理论——强作用手征有效拉氏量的理论特点及研究现状.没有涉及强作用中重夸克有效场论理论,NRQCD理论及它们与手征有效拉氏量结合而形成的理论.

Effective Lagrangian Theory

From view point of modem field theory, all theories for realistic interactionare effective, which come from some more elementary theory. One main feature ofeffective theory is that it include infinite number of interaction terms. Effective theoryis different with standard renormalizable field theory. Here, we focus on a class ofspecial effective theory-effective chiral Lagrangian in strong interaction, discuss itsfeatures and present status of its development. We don't involve heavy quark effechvefield theory and N'RQCD and the combinahon of these theories and effective charalLagrangian.
