Supersymmetric D-brane Bound States with B-field and Higher Dimensional Instantons on Noncommutative Geometry

چکیده
We classify supersymmetric D0-Dp bound states with a non-zero B-field by considering T-dualities of intersecting branes at angles. Especially, we find that the D0-D8 system with the B-field preserves 1/16, 1/8 and 3/16 of supercharges if the B-field satisfies the “(anti-)self-dual” condition in dimension eight. The D0-branes in this system are described by eight dimensional instantons on non-commutative R. We also discuss the extended ADHM construction of the eight-dimensional instantons and its deformation by the B-field. The modified ADHM equations admit a sort of the ‘fuzzy sphere’ (embeddings of SU(2)) solution. e-mail address: [email protected]

Instantons in the U(1) Born-Infeld Theory and Noncommutative Gauge Theory
We derive a BPS-type bound for maximally rotational symmetric configurations in four-dimensional Born-Infeld action with constant B field background. The supersymmetric configuration saturates this bound and is regarded as an analog of instanton in U(1) gauge theory. Furthermore, we find the explicit solutions of this BPS condition. These solutions have a finite action proportional to the insta...
متن کاملEight Dimensional Noncommutative Instantons and D0-D8 Bound States with B-field
We construct some classes of instanton solutions of eight dimensional noncommutative ADHM equations generalizing the solutions of eight dimensional commutative ADHM equations found by Papadopoulos and Teschendorff, and interpret them as supersymmetric D0D8 bound states in a NS B-field. Especially, we consider the D0-D8 system with anti-selfdual B-field preserving 3/16 of supercharges. This syst...
متن کامل(Non-)BPS bound states and D-brane instantons
We study superpotential corrections due to decaying BPS D-brane instantons in four-dimensional N = 1 supersymmetric orientifold compactifications. The relevant objects are certain D-brane instantons which are not invariant under the orientifold projection. We show that they can yield superpotential contributions via a multi-instanton process on the BPS locus. This configuration decays in other ...

متن کاملA Note on Superfields and Noncommutative Geometry
We consider the supersymmetric field theories on the noncommutative R using the superspace formalism on the commutative space. The terms depending on the parameter of the noncommutativity Θ are regarded as the interactions. In this way we construct the N = 1 supersymmetric action for the U(N) vector multiplets and chiral multiplets of the fundamental, anti-fundamental and adjoint representation...
