Hyperfine Effects and Large Corrections
B. Holdom, M. Sutherland
Effects associated with hyperfine mass splitting between pseudo\-scalar and vector mesons may induce surprisingly large corrections in the heavy quark expansion. We…
Gravitational Waves in the Nonsymmetric Gravitational Theory
N. J. Cornish, J. W. Moffat, D. C. Tatarski
We prove that the flux of gravitational radiation from an isolated source in the Nonsymmetric Gravitational Theory is identical to that found in Einstein's General Theory of Relati…
New Perspectives on the BRST-algebraic Structure of String Theory
Bong H. Lian, Gregg J. Zuckerman
Motivated by the descent equation in string theory, we give a new interpretation for the action of the symmetry charges on the BRST cohomology in terms of what we call {\em the Ger…
Simply Modeling Meson HQET
B. Holdom, M. Sutherland
A simple relativistic model of heavy-quark-light-quark mesons is proposed. In an expansion in inverse powers of the heavy quark mass we find that all zeroth and first order heavy q…
Superluminary Universe: A Possible Solution to the Initial Value Problem in Cosmology
J. W. Moffat
The spontaneous breaking of local Lorentz invariance in the early Universe, associated with a first order phase transition at a critical time , generates a large increase in t…
Quantum Gravity, the Origin of Time and Time's Arrow
J. W. Moffat
The local Lorentz and diffeomorphism symmetries of Einstein's gravitational theory are spontaneously broken by a Higgs mechanism by invoking a phase transition in the early Univers…
