Topological index associated with transverse axial vector and vector anomalies in QED
【摘要】 It is shown that a novel anomaly associated with transverse Ward-Takahashi identity exists for a pseudotensor current in QED, and the anomaly gives rise to a topological index of a Dirac operator in terms of an AtiyahSinger index theorem.
