Dilaton tadpoles and D-brane interactions in compact spaces
Raul Rabadan, Frederic Zamora
We analyse some physical consequences when supersymmetry is broken by a set of D-branes and/or orientifold planes in Type II string theories. Generically, there are global dilaton…
Inflationary Scenarios from Branes at Angles
J. Garcia-Bellido, R. Rabadan, F. Zamora
We describe a simple mechanism that can lead to inflation within string-based brane-world scenarios. The idea is to start from a supersymmetric configuration with two parallel stat…
Non-Supersymmetric SO(3)-Invariant Deformations of N=1* Vacua and their Dual String Theory Description
Frederic Zamora
We study the SO(3)-invariant relevant deformations of N=4 SU(N) gauge theory using the methods of Polchinski and Strassler. We present the region of parameter space where the non-s…
On the Operator Product Expansion in Noncommutative Quantum Field Theory
Frederic Zamora
Motivated by the mixing of UV and IR effects, we test the OPE formula in noncommutative field theory. First we look at the renormalization of local composite operators, identifying…
Manifest Supersymmetry in Non-Commutative Geometry
Chong-Sun Chu, Frederic Zamora
We consider the open superstring ending on a D-brane in the presence of a constant NS-NS B field, using the Green-Schwarz formalism. Quantizing in the light-cone gauge, we find tha…
Chiral Symmetry Breaking in the AdS/CFT Correspondence
Jacques Distler, Frederic Zamora
We study the SU(3)-invariant relevant deformation of D=4 N=4 SU(N) gauge theory at large N using the AdS/CFT correspondence. At low energies, we obtain a nonsupersymmetric gauge th…
