One SM*A*S*H to rule them all: A minimal model of particle physics and cosmology
Dr. Andreas Ringwald (DESY)

The discovery of the Higgs boson has marked the completion of the Standard Model of particle physics. However, the latter lacks an explanation of dark matter, of cosmic inflation, of the matter-anti-matter asymmetry of the Universe, of neutrino oscillations and of the feebleness of strong CP violation. A minimal extension of the Standard Model by three extra neutrinos, an extra quark and a scalar particle which get their masses by the spontaneous breaking of a new global Abelian symmetry at the scale of around 1011 GeV may explain all these puzzles in one go.
This model, dubbed “SMASH”, can be probed decisively by upcoming cosmic microwave background and dark matter experiments.
