Intersecting M2– and M5–branes
If an M2–brane intersects an M5–brane the canonical Wess–Zumino action is plagued by a Dirac–anomaly, i.e. a non–integer change of the action under a change of Dirac–brane. We show that this anomaly can be eliminated at the expense of a gravitational anomaly supported on the intersection manifold. Eventually we check that the last one is cancelled by the anomaly produced by the fermions present...
متن کاملM2-branes stretching between M5-branes
A generalization of Nahm’s equation has been recently conjectured by Basu and Harvey to be the BPS condition describing the bound state of a stack of M2branes ending on an M5-brane. In this note exact solutions are presented for the proposed BPS equation – which is from the point of view of the M2-brane world-volume dynamics – with boundary conditions appropriate for M2-branes stretching betwee...
متن کاملLight-cone M5 and multiple M2-branes
We present the light-cone gauge fixed Lagrangian for the M5-brane; it has a residual ‘exotic’ gauge invariance with the group of 5-volume preserving diffeomorphisms, SDiff5, as gauge group. For an M5-brane of topology R 2 ×M3, for closed 3-manifold M3, we find an infinite tension limit that yields an SO(8)-invariant (1 + 2)-dimensional field theory with ‘exotic’ SDiff3 gauge invariance. We show...
متن کاملMatrix Description of Intersecting M5 Branes
Novel 3+1 dimensional N = 2 superconformal field theories (with tensionless BPS string solitons) are believed to arise when two sets of M5 branes intersect over a 3+1 dimensional hyperplane. We derive a DLCQ description of these theories as supersymmetric quantum mechanics on the Higgs branch of suitable 4d N = 1 supersymmetric gauge theories. Our formulation allows us to determine the scaling ...
متن کاملM5-brane in three-form flux and multiple M2-branes
We investigate the Bagger-Lambert-Gustavsson model associated with the Nambu-Poisson algebra as a theory describing a single M5-brane. We argue that the model is a gauge theory associated with the volumepreserving diffeomorphism in the three-dimensional internal space. We derive gauge transformations, actions, supersymmetry transformations, and equations of motions in terms of six-dimensional f...
