Gauge Coupling Unification in the Exceptional Supersymmetric Standard Model
We consider the renormalisation group flow of gauge couplings within the so-called exceptional supersymmetric standard model (E6SSM) based on the low energy matter content of 27 dimensional representations of the gauge group E6, together with two additional non-Higgs doublets. The two–loop beta functions are computed, and the threshold corrections are studied in the E6SSM. Our results show that...
متن کاملGauge 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 کاملMirage gauge coupling unification
We use compact D = 4, N = 1, Type IIB orientifolds as a testing ground for recent ideas about precocious gauge coupling unification and a low energy string scale. We find that certain such orientifolds have the interesting property that gauge couplings receive moduli-dependent corrections which mimic the effect of field theoretical logarithmic running. The effective cut-off scale for the logari...

متن کاملConformality and Gauge Coupling Unification
It has been recently proposed to embed the standard model in a conformal gauge theory to resolve the hierarchy problem, and to avoid assuming either grand unification or low-energy supersymmetry. By model building based on string-field duality we show how to maintain the successful prediction of an electroweak mixing angle with sinθ ≃ 0.231 in conformal gauge theories with three chiral families.
