Quantum Cosmology Aspects Of D3 Branes and Tachyon Dynamics

Anastasios Psinas

We investigate aspects of quantum cosmology in relation to string cosmology systems that are described in terms of the Dirac-Born-Infeld action. Using the Silverstein-Tong model, w…

Gravitational Mediation of Supersymmetry Breaking in Superstring Theory

Tomasz R. Taylor

SUSY breaking and its mediation are among the most important problems of supersymmetric generalizations of the standard model. The idea of gravity-mediated SUSY breaking, proposed…

Note on Mediation of Supersymmetry Breaking from Closed to Open Strings

Ignatios Antoniadis, Tomasz R. Taylor

We discuss the mediation of supersymmetry breaking from closed to open strings, extending and improving previous analysis of the authors in Nucl. Phys. B 695 (2004) 103 [hep-th/040…

Mirage Cosmology of U(1) Gauge Field on Unstable D3 Brane Universe

Anastasios Psinas

An unstable -brane universe governed by the DBI action of the tachyon field minimally coupled to a U(1) gauge boson is examined. The cosmological evolution of this coupled syst…

Open string topological amplitudes and gaugino masses

I. Antoniadis, K. S. Narain, T. R. Taylor

We discuss the moduli-dependent couplings of the higher derivative F-terms $(\Tr W^2)^{h-1}$, where is the gauge N=1 chiral superfield. They are determined by the genus zero to…

The Spectrum of Yang Mills on a Sphere

Alexander Barabanschikov, Lars Grant, Lisa L Huang +1

In this note, we determine the representation content of the free, large N, SU(N) Yang Mills theory on a sphere by decomposing its thermal partition function into characters of the…
