Gauge invariant MSSM inflaton
Abstract
We argue that all the necessary ingredients for successful inflation are present in the flat directions of the Minimally Supersymmetric Standard Model. We show that out of many gauge invariant combinations of squarks, sleptons and Higgses, there are two directions, , and , which are promising candidates for the inflaton. The model predicts more than e-foldings with an inflationary scale of GeV, provides a tilted spectrum with an amplitude of and a negligible tensor perturbation. The temperature of the thermalized plasma could be as low as ~TeV. Parts of the inflaton potential can be determined independently of cosmology by future particle physics experiments.
