Description
I will present a very simple extension of the SM that solves the strong CP-problem and explains dark matter (with the QCD axion), baryogenesis and the smallness of neutrino masses. The model, called SMASH, features a single new physics scale ($\sim 10^11$ GeV), stabilizes the SM effective potential at large field values and produces inflation compatible with current CMB data. Moreover, it is free from unitarity issues (unlike Higgs Inflation) and can be ruled out with future cosmological data and axion experiments.
