Description
Matter-Higgs unification in string-inspired supersymmetric Grand Unified Theories
predicts the existence of colored states in the Higgs multiplets and calls for two
extra generations of Higgs-like fields ('unhiggses'). If these states are present
near the TeV scale, gauge-coupling unification points to the existence of two
distinct scales, 10^15 GeV where right-handed neutrinos and a Pati-Salam symmetry
appear, and 10^18 GeV where complete unification is achieved. Baryon-number
conservation, while not guaranteed, can naturally emerge from an underlying flavor
symmetry. Collider signatures and dark-matter physics may be drastically different
from the conventional MSSM.
