A Minimal Superstring Standard Model II: A Phenomenological Study
Recently, we demonstrated the existence of heterotic–string solutions 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 mode...
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 کاملA 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...

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...
