It is known that the topological A-model allows the existence of 12[D+rank(B)]-dimensional branes, where D is a dimensionality of space-time, and B is a B-field.
Witten showed that the A-model with the target space being the cotangent bundle T∗M to some 3-fold M is equivalent to the Chern-Simons theory defined on this space which is interpreted as an effective theory living on the stack of 3-branes wrapping the base M. More general 3-branes configurations are possible if these branes wrap a Lagrangian submanifold of the embedding space. Generically, in accordance to what stated above, 5-branes are also allowed in a CY 3-fold if one has a non-zero B-field.
Question: Could anybody recommend any literature on these higher-dimensional topological branes and their world volume theories?
