摘要：
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 sin(2) theta similar or equal to 0.231 in conformal gauge theories with three chiral families.
