. Minimal Superstring Standard Model

چکیده
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 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. The phenomenology of theses flat directions is summarized.

Gauge Coupling Unification in Superstring Derived Standard–like Models
I discuss gauge coupling unification in a class of superstring standard–like models, which are derived in the free fermionic formulation. Recent calculations indicate that the superstring unification scale is at O(10GeV ) while the minimal supersymmetric standard model is consistent with LEP data if the unification scale is at O(10)GeV . A generic feature of the superstring standard–like models...
متن کاملConsequences of an Abelian Family Symmetry
The addition of an Abelian family symmetry to the Minimal Supersymmetric Standard Model reproduces the observed hierarchies of quark and lepton masses and quark mixing angles, only if it is anomalous. Green-Schwarz compensation of its anomalies requires the electroweak mixing angle to be sin2 θw = 3/8 at the string scale, without any assumed GUT structure, suggesting a superstring origin for th...

We give a model-independent discussion of fermion masses in four-dimensional het-erotic superstring theories. We discuss the tree level contributions and quantum corrections, including one-loop threshold effects and masses generated as a result of non-perturbative supersymmetry breaking. We also point out that superstring models give rise to a generic µ-term in the effective low energy Lagrangi...
متن کاملMinimal String Unification and Hidden Sector in Z 8 Orbifold Models
We study the minimal supersymmetric standard model derived from the Z8 orbifold models and its hidden sectors. We use a target-space duality anomaly cancellation so as to investigate hidden sectors consistent with the MSSM unification. For the allowed hidden sectors, we estimate the running gauge coupling constants making use of threshold corrections due to the higher massive modes. The calcula...
متن کاملThe Top Quark and other Fermion Masses
Recent developments on approaches to the quark lepton mass problem are reviewed. In particular we discuss dynamical calculations of the top quark mass at (a) the infrared quasifixed point of the Minimal Supersymmetric Standard Model renormalisation group equations, and (b) a strongly first order critical point of the Standard Model effective potential. The phenomenology of symmetric mass matrix...
متن کاملAnnulus Amplitudes in the Minimal Superstring
We study the annulus amplitudes in the (2, 4) minimal superstring theory using the continuum worldsheet approach. Our results reproduce the semiclassical behavior of the wavefunctions of FZZT-branes recently studied in hep-th/0412315 using the dual matrix model. We also study the multi-point functions of neutral FZZT-branes and find the agreement between their semiclassical limit and the worlds...
