Prospects to scrutinise or smash SM*A*S*H

SMASH is an extension of the Standard Model of particle physics which has just the minimal number of fields in order to solve six puzzles of particle physics and cosmology in one smash: vacuum stability, inflation, baryon asymmetry, neutrino masses, strong CP, and dark matter. The parameters of SMASH are constrained by symmetries and requirements to solve these puzzles. This provides various firm predictions for observables which can be confronted with experiments. We discuss the prospects and timeline to scrutinise or smash SMAS*H by cosmic microwave background polarisation experiments, axion haloscopes, and future space-borne gravitational wave detectors.
