Low Energy Effective Action in N=2 Yang-Mills as an Integrated Anomaly | | M. Magro
; I. Sachs

22 Mar 2005 | | Journal: | JHEP 0508 (2005) 006 | | Subject: | hep-th | | Abstract: | Based on chiral ring relations and anomalies, as described by Cachazo, Douglas, Seiberg and Witten, we argue that the holomorphic effective action in N=2 Yang-Mills theory can be understood as an integrated U(1) anomaly from a purely field theory point of view. In particular, we show that the periods of the Riemann surface arising from the generalized Konishi anomaly can be given a physical interpretation without referring to special geometry. We also discuss consequences for the multi-instanton calculus in N=2 Yang-Mills theory. | | Source: | arXiv, hep-th/0503166 | | Services: | Forum | Review | PDF | Favorites | |
