Description
Exclusion of several classes of models due to LHC and astroparticle data has revived interest in grand unification. Typical unified theories predict topological defects. We study a particular SUSY SO(10) model which can produce transitory domain walls near grand unification scale, comparable to the scale of onset of low field inflation. While topologically not stable, the D-parity domain walls are indicated to be formed by Kibble mechanism and are referred to as topological pseudo-defects. We study these in the context of inflation and their potential relation to CMB anomalies.
