SM*A*S*H
  We present a minimal model for particle physics and cosmology. The Standard
Model (SM) particle content is extended by three right-handed SM-singlet
neutrinos N_i and a vector-like quark Q, all of them being charged under a
global lepton number and Peccei-Quinn (PQ) U(1) symmetry which is spontaneously
broken by the vacuum expectation value v_sigma around 10^{11} GeV of a
SM-singlet complex scalar field sigma. Five fundamental problems -- neutrino
oscillations, baryogenesis, dark matter, inflation, strong CP problem -- are
solved at one stroke in this model, dubbed "SM*A*S*H" (Standard
Model*Axion*Seesaw*Higgs portal inflation). It can be probed decisively by
upcoming cosmic microwave background and axion dark matter experiments.
