摘要
对左-右规范场的Wess—Zumino—Witten有效作用量进行联合规范交换,求出了对称和非对称反常,并讨论了反常和Atiyah—Singer指标定理之间关系.
A gauge transformation is given for Wess-Zumino-Witten action of L-R gaugefield, the symmetric and antisymmetric anomalies are calculated, and the relation between anomalyand Atiyah-Singe index theorem is discussed.
