Descrição:
Nowadays we know that, in our Universe, dark matter occupies about 25% of the content, compared to only 5% of the 'visible' ordinary matter. In this talk, we propose that the description of 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. Thus, I propose that on top of the SU(c)(3) x SU(2) x U(l) standard model there is an SU(f)(3) extension - a simple SU(c)(3) x SU(2) x U(l) x SU(f)(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.
