M-branes at angles
In contrast to the current rapid evolution in our understanding of the microscopic degrees of freedom of M-theory, the macroscopic picture has changed very little over the past year. The ‘basic’ ingredients remain D=11 supergravity and its 1/2-supersymmetic solutions: the M-wave, the M-2-brane, the M-5-brane and, in the S KaluzaKlein vacuum, the M-monopole (i.e. EuclideanTaub-Nut times 7-dimens...
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 کاملBranes Intersecting at Angles
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 sup...
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 کاملClassification of Different Branes at Angles
In this paper, we consider two D-branes rotated with respect to each other, and argue that in this way one can find brane configurations preserving 1 16 of SUSY. Also we classify different brane configurations preserving 12 , 1 4 , 3 16 , 1 8 , 1 16 of SUSY.
