Query: Tracking Down the Route to the SM with Inflation and Gravitational Waves   We explore supersymmetric SO(10) models predicting observable proton decay
and various topological defects which produce different shapes and strengths of
gravitational wave backgrounds depending on the scales of intermediate symmetry
breaking and inflation as well. We compare these to their non-supersymmetric
counterparts. By identifying the scales at which gravitational wave signals
appear, we would be able to track down a particular breaking chain and discern
if it has a supersymmetric origin or not. It would also be useful to observe
gravitational waves from more than one source among all possible topological
defects and first order phase transitions for a realistic breaking chain. For
these purposes, we work out specific examples in which the grand unification
and relevant intermediate scales are calculable explicitly. It turns out that
examples with gravitational waves from different sources are quite difficult to
obtain, and the predicted gravitational wave profiles from domain walls and
first order phase transitions obtained in some examples will require detectors
in the kHz to MHz region.
