Branes Intersecting at Angles

چکیده
We show that configurations of multiple D-branes related by SU(N) rotations will preserve unbroken supersymmetry. This includes cases in which two D-branes are related by a rotation of arbitrarily small angle, and we discuss some of the physics of this. In particular, we discuss a way of obtaining 4D chiral fermions on the intersection of Dbranes. We also rephrase the condition for unbroken supersymmety as the condition that a ‘generalized holonomy group’ associated with the brane configuration and manifold is reduced, and relate this condition (in Type IIA string theory) to a condition in eleven dimensions.

Rotating Rotated Branes
We present a class of spacetime rotations that preserve a proportion of spacetime supersymmetry. We then give the rules for superposing these rotations with various branes to construct rotating brane solutions which preserve exotic fractions of supersymmetry. We also investigate the superposition of rotations with intersecting branes at angles and we find new rotating intersecting branes at ang...
متن کاملBranes and instantons intersecting at angles
We study in detail the system of D6 branes and euclidean D2-brane instantons intersecting at angles in type IIA string theory. We find that in the absence of orientifolds the system does not contribute to the low energy superpotential, in agreement with expectations based on effective field theory arguments. We also comment on the implications of our results for dual string theory pictures.
متن کاملSupersymmetric Intersecting D6-branes and Fluxes in Massive Type IIA String Theory
We study N=1 supersymmetric four-dimensional solutions of massive Type IIA supergravity with intersecting D6-branes in the presence NS-NS three-form fluxes. We derive N=1 supersymmetry conditions for the D6-brane and flux configurations in an internal manifold X6 and derive the intrinsic torsion (or SU(3)-structure) related to the fluxes. In the absence of fluxes, N=1 supersymmetry implies that...
متن کاملSupersymmetry of M-branes at Angles
We determine the possible fractions of supersymmetry preserved by two intersecting M5-branes. These include the fractions 3/32 and 5/32 which have not occurred previously in intersecting brane configurations. Both occur in non-orthogonal pointlike intersections of M-5branes but 5/32 supersymmetry is possible only for specific fixed angles. e-mail address: [email protected] e-mail add...
متن کاملHigher Dimensional Recombination of Intersecting D-branes
We study recombination of D-branes system intersecting at more than one angle using super Yang-Mills theory. We find the condensation of an off-diagonal tachyon mode relates to the recombination, as was clarified in a case at one angle in hep-th/0303204. In two angles’ case, after the tachyon mode between two D2-branes condensed, D2-brane charge distributes in the bulk near an intersection poin...
متن کاملMulti-angle Five-Brane Intersections
We find new solutions of IIA supergravity which have the interpretation of intersecting NS-5-branes at Sp(2)-angles on a string preserving at least 3/32 of supersymmetry. We show that the relative position of every pair of NS-5-branes involved in the superposition is determined by four angles. In addition we explore the related configurations in IIB strings and M-theory.
