چکیده

In string compactification on a manifold X , in addition to the string scale and the normal scales of low-energy particle physics, there is a Kaluza-Klein scale 1 R associated with the size of X . We present an argument that generic string models with low-energy supersymmetry have, after moduli stabilization, bulk fields with masses which are parametrically lighter than 1 R . We discuss the implications of these light states for anomaly mediation and gaugino mediation scenarios.

Brane World Susy Breaking from String/M Theory

String and M-theory realizations of brane world supersymmetry breaking scenarios are considered in which visible sector Standard Model fields are confined on a brane, with hidden sector supersymmetry breaking isolated on a distant brane. In calculable examples with an internal manifold of any volume the Kahler potential generically contains brane–brane nonderivative contact interactions couplin...

Dark radiation in anisotropic LARGE volume compactifications

Dark radiation is a compelling extension to ΛCDM: current experimental results hint at ∆Neff & 0.5, which is increased to ∆Neff ' 1 if the recent BICEP2 results are included. In recent years dark radiation has been considered in the context of string theory models such as the LARGE Volume Scenario of type IIB string theory, forging a link between present-day cosmological observations and models...

Scales and hierarchies in warped compactifications and brane worlds

Warped compactifications with branes provide a new approach to the hierarchy problem and generate a diversity of four-dimensional thresholds. We investigate the relationships between these scales, which fall into two classes. Geometrical scales, such as thresholds for Kaluza-Klein, excited string, and black hole production, are generically determined soley by the spacetime geometry. Dynamical s...

Effective Action of Matter Fields in Four-Dimensional String Orientifolds

We study various aspects of the Kähler metric for matter fields in N = 1, 2 orientifold compactifications of type IIB string theory. The result has an infrared-divergent part which reproduces the field-theoretical anomalous dimensions, and a moduli-dependent part which comes from N = 2 sectors of the orientifold. For the N = 2 orientifolds, we also compute the disk amplitude for two matter fiel...

Quantum inhomogeneities in string cosmology

Within two specific string cosmology scenarios — differing in the way the preand post-big bang phases are joined — we compute the size and spectral slope of various types of cosmologically amplified quantum fluctuations that arise in generic compactifications of heterotic string theory. By further imposing that these perturbations become the dominant source of energy at the onset of the radiati...
