Low Energy Dynamical SUSY Breaking Motivated from Superstring Derived Unification

Recently there has been a resurgence of interest in gauge mediated dynamical supersymmetry breaking scenarios. I investigate how low energy dynamical SUSY breaking may arise from superstring models. In a three generation string derived model I propose that the unbroken hidden non–Abelian gauge group at the string scale is SU(3)H with matter multiplets. Due to the small gauge content of the hidd...

Soft Supersymmetry–breaking Terms from Supergravity and Superstring Models

We review the origin of soft supersymmetry–breaking terms in N = 1 supergravity models of particle physics. We first consider general formulae for those terms in general models with a hidden sector breaking supersymmetry at an intermediate energy scale. The results for some simple models are given. We then consider the results obtained in some simple superstring models in which particular assum...

Charge and Color Breaking in Supersymmetry and Superstring

Charge and color breaking minima in SUSY theories might make the standard vacuum unstable. In this talk a brief review of this issue is performed. When a complete analysis of all the potentially dangerous directions in the field space of the theory is carried out, imposing that the standard vacuum should be the global minimum, the corresponding constraints turn out to be very strong and, in fac...

One loop soft supersymmetry breaking terms in superstring effective

We perform a systematic analysis of soft supersymmetry breaking terms at the one loop level in a large class of string effective field theories. This includes the so-called anomaly mediated contributions. We illustrate our results for several classes of orbifold models. In particular, we discuss a class of models where soft supersymmetry breaking terms are determined by quasi model independent ...

Hierarchical Supersymmetry Breaking in Superstring Derived Standard–like Models

We examine the problem of supersymmetry breaking in realistic superstring standard–like models which are constructed in the free fermionic formulation. We impose a supersymmetric vacuum at the Planck scale by requiring vanishing F and D constraints at the cubic level of the superpotential. We then study possible scenarios for supersymmetry breaking by examining the role of nonrenormalizable ter...
