Scalar fields , bent branes , and RG flow
This work deals with braneworld scenarios driven by real scalar fields with standard dynamics. We show how the first-order formalism which exists in the case of four dimensional Minkowski space-time can be extended to de Sitter or anti-de Sitter geometry in the presence of several real scalar fields. We illustrate the results with some examples, and we take advantage of our findings to investig...
متن کاملGravity Duals of Fractional Branes and Logarithmic RG Flow
We study fractional branes in N = 2 orbifold and N = 1 conifold theories. Placing a large number N of regular D3-branes at the singularity produces the dual AdS5 ×X5 geometry, and we describe the fractional branes as small perturbations to this background. For the orbifolds, X = S/Γ and fractional D3-branes excite complex scalars from the twisted sector which are localized on the fixed circle o...

متن کاملComposite electric S-brane solutions with maximal number of branes and several scalar fields
A (n+1)-dimensional cosmological model with a set of scalar fields and antisymmetric (p+2)-form is considered. Some of scalar fields may have negative kinetic terms, i.e. they may describe “phantom” fields. For certain odd dimensions (D = 4m + 1 = 5, 9, 13, ...) and (p + 2)forms (p = 2m−1 = 1, 3, 5, ...) and non-exceptional dilatonic coupling vector ~λ we obtain cosmological-type solutions to t...
متن کاملGauge Fields and D-branes
We prove that self-dual gauge fields in type I superstring theory are equivalent to configurations of Dirichlet 5-branes, by showing that the world-sheet theory of a Dirichlet 1-brane moving in a background of 5-branes includes an " ADHM sigma model. " This provides an explicit construction of the equivalent self-dual gauge field.
