Description
The standard model extended by three vector-like families with masses
of order 1 TeV -- 100 TeV allows for unification of gauge
couplings. The values of gauge couplings at the electroweak scale are
highly insensitive to fundamental parameters. The grand unification
scale is large enough to avoid the problem with fast proton decay. The
electroweak minimum of the Higgs potential is stable.
