Partition Function Zeros in Non-compact QED

A. Ali Khan, I. Barbour

The lowest zeros of the lattice partition function for non-compact QED are found in the complex fermion mass plane on , and lattices at intermediate values of the…

An Exact Calculation of the Energy Density of Cosmological Gravitational Waves

L. E. Mendes, A. B. Henriques, R. G. Moorhouse

In this paper we calculate the Bogoliubov coefficients and the energy density of the stochastic gravitational wave background for a universe that undergoes inflation followed by ra…

Darboux Transformations from Reductions of the KP Hierarchy

J J C NIMMO

The use of effective Darboux transformations for general classes Lax pairs is discussed. The general construction of ``binary'' Darboux transformations preserving certain propertie…

A Precise Determination of from Lattice QCD

C. T. H. Davies, K. Hornbostel, G. P. Lepage +3

We present a new determination of the QCD strong coupling constant based on precise lattice calculations of the spectrum. The largest systematic uncertainty in previous such de…

Precision Upsilon Spectroscopy from Nonrelativistic Lattice QCD

C. T. H. Davies, K. Hornbostel, A. Langnau +4

The spectrum of the Upsilon system is investigated using the Nonrelativistic Lattice QCD approach to heavy quarks and ignoring light quark vacuum polarization. We find good agreeme…

A New Determination of M_b Using Lattice QCD

C. T. H. Davies, K. Hornbostel, A. Langnau +5

Recent results from lattice QCD simulations provide a realistic picture, based upon first principles, of~ physics. We combine these results with the experimentally measured mass…
