Implications of LEP Results for SO(10) Grandunification with Two Intermediate Stages
Abstract
We consider the breaking of the grand unification group SO(10) to the standard model gauge group through several chains containing two intermediate stages. Using the values of the gauge coupling constants at scale MZ derived from recent LEP data, we determine the range of their intermediate and unification scales. In particular, we identify those chains that permit new gauge structure at relatively low energy ( 1\, TeV).
