Abstract :

Three of the important puzzles in cosmology relate to the origin of baryon asymmetry in the Universe, the nature of dark matter and the cosmic coincidence that the amount of dark matter and visible matter are comparable. In this talk, I will discuss about the classes of models where baryon asymmetry and dark matter have a common origin within the framework of U extensions of the standard model and of the minimal supersymmetric standard model. In one model all of the fundamental interactions do not violate lepton number, and the total B-L in the Universe vanishes, which is quite different from previous mechanisms that baryon or lepton number are violated in generating the matter and anti-matter asymmetry. In addition, one may also generate a normal hierarchy of neutrino masses and mixings in conformity with the current data from Daya Bay reactor neutrino experiment.
