Remarks on the M5-brane
نویسنده
چکیده
The fivebrane of M theory – the M5-brane – is an especially interesting object. It plays a central role in a geometric understanding of the Seiberg–Witten solution of N=2 D=4 gauge theories as well as in certain new 6d quantum theories. The low energy effective action is an interacting theory of a (2,0) tensor multiplet. The fact that this multiplet contains a two-form gauge field with a self-dual field strength poses special challenges. Recent progress in addressing those challenges is reviewed.

Intersecting Noncommutative M5-branes from Covariant Open Supermembrane
We study intersecting noncommutative (NC) M5-branes from κ-invariance of an open supermembrane action with constant three-form fluxes. The κ-invariance gives rise to possible D-brane configurations for which projection operators can be determined. We construct projection operators for two types of 1/4 BPS intersecting NC M5-branes. The one is an intersection of two NC M5-branes: NC M5⊥NC M5 (3)...

Recently, noncommutative theories have received renewed interest, after it was found that noncommutative theories can be naturally realized in M theory compactified in the presence of constant three-form field background @1# and within string theories as the worldvolume theory of a D-brane with a nonzero constant Neveu-Schwarz ~NS! B field @2,3#. In the case of a D-brane with a constant magneti...
متن کاملThe Off-shell M5-brane and Non-Perturbative Gauge Theory
M5-branes wrapping a holomorphic curve in a Calabi-Yau manifold can be used to construct four-dimensional N = 1 gauge theories. In this paper we will consider M5-brane configurations corresponding to N = 2 theories broken to N = 1 by a superpotential for the adjoint scalar field. These M5-brane configurations can be obtained by lifting suitable intersecting brane configurations in type IIA, or ...
متن کاملComments on Brane Configurations with Semi-infinite D4 Branes
We consider four dimensional supersymmetric gauge field theories from brane configurations with the matter content given by semi-infinite D4 branes ending on both sides of NS branes. In M theory configuration, we discuss the splitting of the M5 brane into infinite cylindrical M5 branes (which decouple) and transversal M5 brane. The splitting condition appears naturally from the consistency of t...
متن کاملBrane-intersection Dynamics from Branes in Brane Backgrounds
We derive the dynamics of M-brane intersections from the worldvolume action of one brane in the background supergravity solution of another one. In this way we obtain an effective action for the self-dual string boundary of an M2-brane in an M5-brane, and show that the dynamics of the 3-brane intersection of two M5-branes is described by a Dirac-Born-Infeld action.
