Anomalies for Spinor Currents in a Massless Yang-Mills Theory

摘要

Anomalies of the divergences of the spinor currents in a supersymmetric gauge theory are studied in the perturbation theory. The linearly divergent nature of the loop integrations leads to the two kinds of anomalies. The divergent parts, which essentially give the vertex renormalization constant, contribute to the anomaly for the conformal spinor current, while the finite surface terms give rise to the anomaly for the first spinor current. The anomaly for the first current, however, can be removed by the redefinition of the gauge invariant conserved current. (Atomindex citation 09:415183)
