Summary: | Here, we describe how quartic (λφ<sup>4</sup>) inflation with non-minimal coupling to gravity is realized in realistic supersymmetric SO(10)models. In a well-motivated example the 16 -$\overline{16}$ Higgs multiplets, which break SO(10) to SU(5) and yield masses for the right-handed neutrinos, provide the inflaton field φ. Thus, leptogenesis is a natural outcome in this class of SO(10) models. Moreover, the adjoint (45-plet) Higgs also acquires a GUT scale value during inflation so that the monopole problem is evaded. The scalar spectral index n<sub>s</sub> in good agreement with the observations and r, the tensor to scalar ratio, is predicted for realistic values of GUT parameters to be of order 10<sup>-3</sup>-10<sup>-2</sup> N=1 Supergravity; Matter; Cosmology; Gravitino; Origin; Decay. |
