A Minimal Superstring Standard Model I: Flat Directions
Three family SU(3)C × SU(2)L ×U(1)Y string models in several constructions generically possess two features: (i) an extra local anomalous U(1)A and (ii) numerous (often fractionally charged) exotic particles beyond those in the minimal supersymmetric model (MSSM). Recently, we showed that just below the string scale, the observable sector effective field theory of such a free fermionic string m...
متن کاملNon–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...
متن کاملPhenomenology 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...
متن کامل. Minimal Superstring Standard Model
I review 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...
متن کاملPhenomenological Survey of a Minimal Superstring Standard Model 1 Flat Directions in Three–generation Heterotic–string Models
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 dir...
