A Note on Modulus-dominated SUSY-breaking

TL;DR

This paper investigates models where supersymmetry-breaking is primarily driven by Kahler moduli and the dilaton, analyzing the consistency of B-parameter and tan(beta) values at different energy scales within various string-inspired frameworks.

Contribution

It provides a self-consistent analysis of the B-parameter in modulus-dominated SUSY-breaking models, including M-theory and Type IIB flux compactifications.

Findings

Viability of modulus-dominated SUSY-breaking models assessed

Consistency conditions between B-parameter and tan(beta) established

Implications for GUT-scale soft-terms discussed

Abstract

In models where supersymmetry-breaking is dominated by the Kahler moduli and/or the universal dilaton, the B-parameter at the unification scale should be consistent with the value of tan(beta) at the electroweak scale determined by minimization of the Higgs potential triggering REWSB. We study such models employing a self-consistent determination of the B-parameter. In particular, we study the viability of a generic model, as well as M-theory and Type IIB flux compactifications with modulus-dominated supersymmetric soft-terms from the GUT scale, M_{GUT}=2x10^{16}GeV.
