DESCRIPTION:Carlos Tamarit\nA minimal extension of the Standard Model (SM)
  providing a complete and consistent picture of particle physics and cosmo
 logy up to the Planck scale is presented. We add to the SM three right-han
 ded SM-singlet neutrinos\, a new vector-like color triplet fermion and a c
 omplex SM singlet scalar σ whose vacuum expectation value at ∼10^11 GeV
  breaks lepton number and a Peccei-Quinn symmetry simultaneously. Primordi
 al inflaton is produced by a combination of σ and the SM Higgs. Baryogene
 sis proceeds via thermal leptogenesis. At low energies\, the model reduces
  to the SM\, augmented by seesaw-generated neutrino masses\, plus the axio
 n\, which solves the strong CP problem and accounts for the dark matter in
  the Universe. The model can be probed decisively by the next generation o
 f cosmic microwave background and axion dark matter experiments
