Multipartite Dark Matter
Qing-Hong Cao, Ernest Ma, Jose Wudka +1
Dark matter (comprising a quarter of the Universe) is usually assumed to be due to one and only one weakly interacting particle which is neutral and absolutely stable. We consider…
A(4) Symmetry and Neutrinos
Ernest Ma
I recount briefly the history of neutrino tribimaximal mixing and the use of the discrete family symmetry A(4) in obtaining it.
SU(5) Completion of the Dark Scalar Doublet Model of Radiative Neutrino Mass
Ernest Ma
Adding a second scalar doublet (eta^+,eta^0) and three neutral singlet fermions N_{1,2,3} to the Standard Model of particle interactions with a new Z_2 symmetry, it has been shown…
Multiplicative Conservation of Baryon Number and Baryogenesis
Ernest Ma
In the canonical seesaw mechanism of neutrino mass, lepton number is only multiplicatively conserved, which enables the important phenomenon of leptogenesis to occur, as an attract…
Singlet fermion dark matter and electroweak baryogenesis with radiative neutrino mass
K. S. Babu, Ernest Ma
The model of radiative neutrino mass with dark matter proposed by one of us is extended to include a real singlet scalar field. There are then two important new consequences. One i…
Near Tribimaximal Neutrino Mixing with Delta(27) Symmetry
Ernest Ma
The discrete subgroup Delta(27) of SU(3) has the interesting multiplication rule 3 X 3 = bar{3} + bar{3} + bar{3}, which is used to obtain near tribimaximal neutrino mixing. Using…
