A Note on Non-Commutative Field Theory and Stability of Brane-Antibrane Systems
Abstract
It has been conjectured that a pair of D5 - anti D5 branes wrapped on some non-trivial two cycle of a Calabi-Yau manifold becomes a stable BPS D3 brane in the presence of a very large B field and magnetic fluxes on their worldvolumes. We discuss this by considering the non-commutative field theory on the worldvolume of the pair of branes whose field multiplication is made with respect to two different * products due to the presence of different F fields on the two branes. The tachyonic field becomes massless for a specific choice of the magnetic fluxes and it allows a trivial solution. Our discussion generalizes recent results concerning stability of brane-antibrane systems on Calabi-Yau spaces to the case of non-commutative branes.
