8 Dec 1998 | Journal: | Nucl.Phys. B552 (1999) 291-315 | Subject: | hep-th | Abstract: | We study anomalous Wess-Zumino couplings of D-branes and O-planes in a general background and derive them from a direct string computation by factorizing in the RR channel various one-loop amplitudes. In particular, we find that Op-planes present gravitational anomalous couplings involving the Hirzebruch polynomial L, similarly to the roof genus A encoding Dp-brane anomalous couplings. We determine, in each case, the precise dependence of these couplings on the curvature of the tangent and normal bundles. | Source: | arXiv, hep-th/9812071 | Services: | Forum | Review | PDF | Favorites |
