Higgs-squark-slepton inflation from the MSSM

The inflation within the minimal supersymmetric standard model (MSSM) is proposed, where the inflaton field is a combination of the Higgs, squark, and slepton states. While the inflationary phase is fully governed by the electron Yukawa superpotential coupling, the fields' condensates float along the flat D-term trajectory. This predicts the MSSM parameter tan beta similar or equal to 13.1 determined via the value of the curvature perturbation amplitude. The values of the scalar spectral index and the tensor-to-scalar ratio are predicted to be n(s) similar or equal to 0.966 and r = 0.00118. The postinflation reheating of the Universe proceeds by the radiative decay of the inflaton to the two gluons (phi -> gg) with the reheating temperature T-r similar or equal to 1.4 x 10 7 GeV.
