Moduli and Brane Intersections
نویسنده
چکیده
We discuss the worldvolume description of intersecting D-branes, including the metric on the moduli space of deformations. We impose a choice of static gauge that treats all the branes on an equal footing and describes the intersection of D-branes as an embedded special Lagrangian three-surface. Some explicit solutions to these equations are given and their interpretation in terms of a superpotential on moduli space is discussed. These surfaces are interpreted in terms of the flat direction of a non-Abelian superpotential and imply the existance of non-compact G2 manifolds. [email protected]

P-brane Black Holes for General Intersections
Black hole generalized p -brane solutions for a wide class of intersection rules are presented. The solutions are defined on a manifold that contains a product of n−1 Ricci-flat internal spaces. They are defined up to moduli functions Hs = Hs(R) obeying a non-linear differential equations (equivalent to Toda-type equations) with certain boundary conditions imposed. Using conjecture on polynomia...
متن کاملGauge Threshold Corrections in Intersecting Brane World Models
We calculate the one–loop corrections to gauge couplings in N=1 supersymmetric brane world models, which are realized in an type IIA orbifold/orientifold background with several stacks of D6 branes wrapped on 3–cycles with non–vanishing intersections. Contributions arise from both N=1 and N=2 open string subsectors. In contrast to what is known from ordinary orbifold theories, N=1 subsectors do...
متن کاملOn Brane Solutions with Intersection Rules Related to Lie Algebras
The review is devoted to exact solutions with hidden symmetries arising in a multidimensional gravitational model containing scalar fields and antisymmetric forms. These solutions are defined on a manifold of the form M = M0 × M1 × . . . × Mn , where all Mi with i ≥ 1 are fixed Einstein (e.g., Ricci-flat) spaces. We consider a warped product metric on M . Here, M0 is a base manifold, and all sc...
متن کامل[ensl-00343145, v1] Intersecting Attractors
We apply the entropy formalism to the study of the near-horizon geometry of extremal black p-brane intersections in D > 5 dimensional supergravities. The scalar flow towards the horizon is described in terms an effective potential given by the superposition of the kinetic energies of all the forms under which the brane is charged. At the horizon active scalars get fixed to the minima of the eff...
