The new Minimal Standard Model
چکیده انگلیسی
We construct the new Minimal Standard Model that incorporates the new discoveries of physics beyond the Minimal Standard Model (MSM): dark energy, non-baryonic dark matter, neutrino masses, as well as baryon asymmetry and cosmic inflation, adopting the principle of minimal particle content and the most general renormalizable Lagrangian. We base the model purely on empirical facts rather than aesthetics. We need only six new degrees of freedom beyond the MSM. It is free from excessive flavor-changing effects, CP violation, too-rapid proton decay, problems with electroweak precision data, and unwanted cosmological relics. Any model of physics beyond the MSM should be measured against the phenomenological success of this model.
