Anomalies in noncommutative gauge theories, Seiberg-Witten transformation and Ramond-Ramond couplings | | Rabin Banerjee

23 Dec 2002 | | Journal: | Int.J.Mod.Phys. A19 (2004) 613 | | Subject: | hep-th | | Abstract: | We propose an exact expression for the unintegrated form of the star gauge invariant axial anomaly in an arbitrary even dimensional gauge theory. The proposal is based on the inverse Seiberg-Witten map and identities related to it, obtained earlier by comparing Ramond-Ramond couplings in different decsriptions. The integrated anomalies are expressed in terms of a simplified version of the Elliott formula involving the noncommutative Chern character. These anomalies, under the Seiberg-Witten transformation, reduce to the ordinary axial anomalies. Compatibility with existing results of anomalies in noncommutative theories is established. | | Source: | arXiv, hep-th/0301174 | | Services: | Forum | Review | PDF | Favorites | |
