Phenomenological Survey of a Minimal Superstring Standard Model 1 Flat Directions in Three–generation Heterotic–string Models

نویسنده

چکیده

We discuss a heterotic–string solution in which the observable sector effective field theory just below the string scale reduces to that of the MSSM, with the standard observable gauge group being just SU(3)C × SU(2)L × U(1)Y and the SU(3)C × SU(2)L × U(1)Y –charged spectrum of the observable sector consisting solely of the MSSM spectrum. Associated with this model is a set of distinct flat directions of vacuum expectation values (VEVs) of fields that all produce solely the MSSM spectrum. Some of these directions only involve VEVs of non–Abelian singlet fields while others also contain VEVs of non–Abelian charged fields.

Non–Abelian Flat Directions in a Minimal Superstring Standard Model

Recently, by studying exact flat directions of non–Abelian singlet fields, we demonstrated the existence of free fermionic heterotic–string models in which the SU(3)C × SU(2)L × U(1)Y –charged matter spectrum, just below the string scale, consists solely of the MSSM spectrum. In this paper we generalize the analysis to include VEVs of non–Abelian fields. We find several, MSSM–producing, exact n...

Phenomenology of Non-Abelian Flat Directions in a Minimal Superstring Standard Model

Recently, we presented the first non-Abelian flat directions that produce from a heterotic string model solely the three-generation MSSM states as the massless spectrum in the observable sector of the low energy effective field theory. In this paper we continue to develop the systematic techniques for the analysis of nonrenormalizable superpotential terms and non-Abelian flat direction in reali...

Classification of Flat Directions in Perturbative Heterotic Superstring Vacua with Anomalous U ( 1 )

We develop techniques to classify Dand F -flat directions for N = 1 supersymmetric string vacua of the perturbative heterotic string theory, which possess an anomalous U(1) gauge group at the tree level. Genus-one corrections generate a Fayet-Iliopoulos term for the D-term of U(1)A, which is canceled by non-zero vacuum expectation values (VEVs) of certain massless multiplets in such a way that ...
