Abstract
We show that a supersymmetric renormalizable theory based on gauge group SO(10)SO(10) and Higgs system 10⊕210⊕126⊕126‾ with no scale supergravity can lead to a Starobinsky kind of potential for inflation. Successful inflation is possible in the cases where the potential during inflation corresponds to SU(3)C×SU(2)L×SU(2)R×U(1)B-LSU(3)C×SU(2)L×SU(2)R×U(1)B-L, SU(5)×U(1)SU(5)×U(1) and flipped SU(5)×U(1)SU(5)×U(1) intermediate symmetry with a 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.
