D2-brane RR-charge on SU(2)

High Energy Physics - Theory 2009-11-07 v1

Abstract

We compute RR charges of D2-branes on a background with H-field which belongs to a nontrivial cohomology class. We discover that the RR charge depends on the configuration of the background `electric' RR field. This result explains the ambiguity in the definition of the RR charge previously observed in the SU(2) WZW model.
