GAUGE THEORY AND MORE — ANOTHER SOLUTION FOR THE DARK MATTER

Abstract

These days we learn that, in our Universe, the dark matter occupies about 25% of the content, compared to only 5% of the "visible" ordinary matter. We propose that the description of the dark matter would be an extension of the Standard Model - a gauge theory. We all know that in the Standard Model we have three generations but still don't know why - the so-called "family problem". On other hand, in view of the masses and oscillations, the neutrinos now present some basic difficulty in the Standard Model. In this note, I propose that on top of the SUc(3)×, SU(2) × U(1) standard model there is an SUf(3) extension - a simple SUc(3) × SU(2) × U(1) × SUf(3) extended standard model. The family gauge bosons (familons) are massive through the so-called "colored" Higgs mechanism while the remaining Higgs particles are also massive. The three neutrinos, the electron-like, muon-like, and tao-like neutrinos, form the basic family triplets. Hopefully all the couplings to the "visible" matter are through the neutrinos, explaining why the dark matter is more than the visible matter in our Universe.
