Abstract

Using the permutation symmetry between the product of several group manifolds and the construction of symmetry-breaking (B-type) branes using orbifolds in combination with T-duality, we define several new classes of branes on products of group manifolds which mix the submanifolds and break part of the diagonal chiral algebra of the theory. We perform a Langrangian analysis as well as a boundary CFT construction of these branes and find agreement between the two methods.
