摘要:
We show how to consistently renormalize N = 1 and N = 2 supersymmetric Yang-Mills theories in flat space with a local (i.e. spacetime-dependent) renormalization scale in a holomorphic scheme. The action gets enhanced by a term proportional to derivatives of the holomorphic coupling. In the N = 2 case, this new action is exact at all orders in perturbation theory.
