标题： The power of the anomaly consistency condition for the Master Ward Identity: Conservation of the non-Abelian gauge current

摘要： 通过对局域规范变换以适当的方式延拓到Faddeev-Popov鬼场，可以得到总作用量的一个对称性，即Yang-Mills作用量加上一个规范固定项（在λ-规范下）以及鬼场作用量。 异常的主Ward恒等式（针对这个作用量和扩展后的局域规范变换）表明相关的Noether流——“相互作用下的‘规范流’”——除了异常外是守恒的。 证明了除了可以通过有限重整化轻松消除的项之外，所有可能的异常都被主Ward恒等式的异常一致性条件排除，该条件最近在参考文献[8]中导出。 显示英文摘要

摘要： Extending local gauge tansformations in a suitable way to Faddeev-Popov ghost fields, one obtains a symmetry of the total action, i.e., the Yang-Mills action plus a gauge fixing term (in a lambda-gauge) plus the ghost action. The anomalous Master Ward Identity (for this action and this extended, local gauge transformation) states that the pertinent Noether current -- the interacting ``gauge current'' -- is conserved up to anomalies. It is proved that, apart from terms being easily removable (by finite renormalization), all possible anomalies are excluded by the consistency condition for the anomaly of the Master Ward Identity, recently derived in refenrence [8].
