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 کاملThe geometry of M5-branes and TQFTs
The calculation of the partition function for N M5-branes is addressed for the case in which the worldvolume wraps a manifold T 2 × M4, where M4 is simply connected and Kaehler. This is done in a compactification of M-theory which induces the Vafa-Witten theory on M4 in the limit of vanishing torus volume. The results follow from the equivalence of the BPS spectrum counting in the complementary...
متن کاملSupergravity M5-branes wrapped on Riemann surfaces and their QFT duals
We find solutions of 11-dimensional supergravity for M5-branes wrapped on Riemann surfaces. These solutions preserve N = 2 fourdimensional supersymmetry. They are dual to N = 2 gauge theories, including non-conformal field theories. We work out the case of N = 2 Yang-Mills in detail.
