D-branes and geometrical kappa-symmetry
New extended superspaces associated with topological charge algebras of the D-brane are used to construct D-brane actions without worldvolume gauge fields. The actions are shown to be kappa-symmetric under an appropriately chosen right group action.
متن کاملStrings, boundary fermions and coincident D-branes
The appearance in string theory of higher-dimensional objects known as Dbranes has been a source of much of the interesting developements in the subject during the past ten years. A very interesting phenomenon occurs when several of these D-branes are made to coincide: The abelian gauge theory living on each brane is enhanced to a non-abelian gauge theory living on the stack of coincident brane...
متن کاملMaking manifest the symmetry enhancement for coincident BPS branes
We consider g coincident M-5-branes on top of each other, in the KK monopole background Q of multiplicity N . The worldvolume of each M-5-brane is supposed to be given by the local product of the four-dimensional spacetime R and an elliptic curve. In the coincidence limit, all these curves yield a single (Seiberg-Witten) hyperelliptic curve Σg, while the gauge symmetry is enhanced to U(N). We m...
متن کاملAdS/CFT correspondence and coincident D-6-branes
A relation between confinement and Maldacena conjecture is briefly discussed. The gauge symmetry enhancement for two coincident D-6-branes is analyzed from the viewpoint of the hypermultiplet low-energy effective action given by the N=2 supersymmetric non-linear sigma-model with the Eguchi-Hanson (ALE) target space. The most attractive mechanism of color confinement in QCD is known to be the du...
متن کاملD-branes, Cyclic Symmetry and Noncommutative Geometry
We investigate the open string modes, describing the world-volume of a D p-brane, for its cyclic symmetry in presence of a magnetic field. It is argued that the constant coordinate modes receive non-perturbative correction. We show that they introduce the notion of noncommutativity on the D p-brane world-volume and make it UV-renormalizable. An analogy between cyclic symmetry (α-corrections) an...
