Generating Neutrino Mass in the 331 Model
M. B. Tully, G. C. Joshi
A mechanism for generating small tree-level Majorana mass for neutrinos is implemented in the 331 Model. No additional fermions or scalars need to be added, and no mass scale great…
Mass Bounds for Flavour Mixing Bileptons
M. B. Tully, G. C. Joshi
Mass bounds for doubly-charged bilepton gauge bosons are derived from constraints on fermion pair production at LEP and lepton-flavour violating charged lepton decays. The limit ob…
A dichotomy between HSB and LSB galaxies
Marc Verheijen, Brent Tully
A complete sample of spiral galaxies in the Ursa Major cluster is imaged at various optical wavelengths and in the Near-Infrared K'-band. HI rotation curves were obtained for all g…
The Scalar Sector in 331 Models
M. B. Tully, G. C. Joshi
We calculate the exact tree-level scalar mass matrices resulting from symmetry breaking using the most general gauge-invariant scalar potential of the 331 model, both with and with…
Fermion Masses and Mixing in 331 Models with Horizontal Symmetry
M. B. Tully, G. C. Joshi
The possibility of adding an SU(2) horizontal symmetry to the 331 model is studied. It is found that simple, anomaly-free fermion assignments can be made which lead to plausible re…
