Neutrino clustering and the Z-burst model
B. H. J. Mckellar, M. Garbutt, G. J. Stephenson +1
The possibility that the observed Ultra High Energy Cosmic Rays are generated by high energy neutrinos creating "Z-bursts" in resonant interactions with the background neutrinos ha…
A See-Saw Mechanism with light sterile neutrinos
B. H. J. McKellar, G. J. Stephenson, T. Goldman +1
The usual see-saw mechanism for the generation of light neutrino masses is based on the assumption that all of the flavours of right-handed (more properly, sterile) neutrinos are h…
MSW Without Matter
T. Goldman, B. H. J. McKellar, G. J. Stephenson
We examine the effects of a scalar field, coupled only to neutrinos, on oscillations among weak interaction current eigenstates. The existence of a real scalar field is manifested…
Quark Model Calculations Of Symmetry Breaking in Parton Distributions
C. J. Benesh, T. Goldman, G. J. Stephenson
Using a quark model, we calculate symmetry breaking effects in the valence quark distributions of the nucleon. In particular, we examine the breaking of the quark model SU(4) symme…
Observable Consequences of a Scalar Boson Coupled only to Neutrinos
G. J. Stephenson, T. Goldman
We have examined the consequences of assuming the existence of a light scalar boson, weakly coupled to neutrinos, and not coupled to any other light fermions. For a range of parame…
