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…
Antimatter Gravity and Antihydrogen Production
Michael H. Holzscheiter, T. Goldman, Michael Martin Nieto
Certain modern theories of gravity predict that antimatter will fall differently than matter in the Earth's gravitational field. However, no experimental tests of gravity on antima…
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…
Theoretical Motivation for Gravitation Experiments on Ultra-Low Energy Antiprotons and Antihydrogen
Michael Martin Nieto, T. Goldman, John D. Anderson +2
We know that the generally accepted theories of gravity and quantum mechanics are fundamentally incompatible. Thus, when we try to combine these theories, we must beware of physica…
(J,0)+(0,j) Representation Space: Dirac-Like Construct
D. V. Ahluwalia, M. B. Johnson, T. Goldman
This is first of the two invited lectures presented (by D. V. Ahluwalia) at the ``XVII International School of Theoretical Physics: Standard Model and Beyond' 93.'' The text is ess…
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…
