Abstract

We implement inflation within a realistic supersymmetric SO(10) model in which the doublet-triplet splitting is realized through the Dimopoulos-Wilczek mechanism, the MSSM \ensuremathμ problem is resolved, and Higgsino mediated dimension five nucleon decay is heavily suppressed. The cosmologically unwanted topological defects are inflated away, and from \ensuremathδT/T, the B\ensuremath-L breaking scale is estimated to be of order 10¹⁶--10¹⁷ GeV. Including supergravity corrections, the scalar spectral index n_s=0.99\ifmmode±\else\textpm\fi0.01, with |dn_s/dlnk|\ensuremath\lesssim10^\ensuremath-3.
