Abstract
The possibility of SO(10) as a grand unification group of the standard SU(2) L × U(1) Y × SU(3) c , was first noted by Georgi [1] and Fritzsch and Minkowski [1]. Unlike SU(5), SO(10) is a group of rank 5 with the extra diagonal generator of SO(10) being B — L as in the left-right symmetric groups. The advantages of SO(10) over SU(5) grand unification are that:
-
(a)
only one 16-dimensional spinor representation of SO(10) has the right quantum numbers to accommodate all fermions (including the right-handed neutrino) of one generation;
-
(b)
the gauge interactions of SO(10) conserve parity thus making parity a part of a continuous symmetry: this has the advantage that it avoids the cosmological domain wall problem associated with parity symmetry breakdown; and
-
(c)
it is the minimal left-right symmetric grand unified model that gauges the B — L symmetry and is the only other simple grand unification group that does not need mirror fermions [2]. The model does not have any global symmetries.
