Abstract
We show that a renormalizable theory based on gauge group SO(10) and Higgs system 10 $$\oplus $$ 210 $$\oplus $$ 126 $$\oplus $$ $${\overline{\mathbf{126}}}$$ with no scale supergravity can lead to a Starobinsky kind of potential for inflation. Successful inflation is possible in cases where the potential during inflation corresponds to $$SU(3)_\mathrm {C} \times SU(2)_\mathrm {L} \times SU(2)_\mathrm {R} \times U(1)_{\mathrm {B-L}}$$ , $$SU(5)\times U(1)$$ and flipped $$SU(5)\times U(1)$$ symmetries with suitable choice of superpotential parameters. The reheating in such a scenario can occur via non-perturbative decay of inflaton, i.e. through ‘preheating’. After the end of reheating, when Universe cools down, the finite-temperature potential can have a minimum which corresponds to MSSM.
