One - loop corrections to the D 3 brane action
نویسنده
چکیده
We calculate one-loop corrections to the effective Lagrangian for the D3 brane. We perform the gauge-fixing of the κ-symmetric Born-Infeld D3 brane action in the flat background using Killing gauge. The linearized supersymmetry of the gaugefixed action coincides with that of the N = 4 Yang-Mills theory. We use the helicity amplitude and unitarity technique to calculate the one-loop amplitudes at order α. The counterterms and the finite 1-loop corrections are of the form (∂F ) and their supersymmetric generalization. This is to be contrasted with the Born-Infeld action which contains (F ) and other terms which do not depend on derivatives of the vector field strength. e-mail: [email protected].

Gauge 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 کاملLoop Corrected D-brane Stability Conditions
In type-II string theory compactifications on Calabi-Yau manifolds, topological string theory partition functions give a class of exact F-terms in the four dimensional effective action. We point out that in the background of constant self-dual field strength, these terms deform the central charges for D-branes wrapping Calabi-Yau manifold to include string loop corrections. We study the corresp...

In this review we describe the general geometrical framework of brane world constructions in orientifolds of type IIA string theory with D6-branes wrapping 3-cycles in a Calabi-Yau 3-fold. These branes generically intersect in points on the internal space, and the patterns of intersections govern the chiral fermion spectra. We discuss how the open string spectra in intersecting brane models are...
متن کاملCurvature terms in D-brane actions and their M-theory origin
We derive the complete (curvature) terms of effective D-brane actions, for arbitrary ambient geometries and world-volume embeddings, at lowest order (disk-level) in the string-loop expansion. These terms reproduce the o(α′ ) corrections to string scattering amplitudes, and are consistent with duality conjectures. In the particular case of the D3-brane with trivial normal bundle, considerations ...
متن کاملHeterotic / Type-i Duality and D-brane Instantons
We study heterotic/type I duality in d = 8, 9 uncompactified dimensions. We consider the special (“BPS saturated”) F4 and R4 terms in the effective one-loop heterotic action, which are expected to be non-perturbatively exact. Under the standard duality map these translate to tree-level, perturbative and non-perturbative contributions on the type I side. We check agreement with the one-loop open...
