A Comparison of Clover and Wilson Spectroscopy in the Presence of Dynamical Quarks
Sara Collins, Robert G. Edwards, Urs M. Heller +1
We present preliminary results of light hadron spectroscopy using valence, tadpole-improved, Clover fermions on an ensemble of gauge configurations generated with 2 flavors of stag…
Upsilon and J/Psi Spectroscopy Using Clover Fermions in the Presence of Dynamical Quarks
Sara Collins, Robert G. Edwards, Urs M. Heller +1
We calculate spin averaged splittings in the bottomonium and charmonium systems using the clover action. We compare static and kinetic masses of heavy-heavy and heavy-light mesons…
The Phase Structure of the Schwinger Model on the Lattice with Wilson Fermions in the Hartree-Fock Approximation
Ivan Horvath
The phase diagram of the Schwinger model on the lattice with one and two degenerate flavours of Wilson fermions is investigated in the Hartree-Fock approximation. In case of a sing…
Chiral Symmetry Breaking in Strongly Coupled Quenched QED Using the Dyson-Schwinger Equation Formalism
A. G. Williams, F. T. Hawes
We study chiral symmetry breaking in quenched strong-coupling QED in arbitrary covariant gauge within the Dyson-Schwinger equation formalism. A recently developed numerical ren…
The equation of state for two flavor QCD
C. Bernard, T. Blum, C. DeTar +8
We improve the calculation of the equation of state for two flavor QCD by simulating on lattices at appropriate values of the couplings for the deconfinement/chiral symmetr…
Surface modes and parity violation in Schwinger model on the lattice
Ivan Horvath
The phase diagram of the Schwinger model on the lattice with Wilson fermions is investigated in the Hartree-Fock approximation. In case of single flavour (not directly amenable to…
The continuum limit in the quenched approximation
C. Bernard T. Blum, C. DeTar, Steven Gottlieb +6
Previous work at with quenched staggered quarks is extended with new calculations at 5.85 and 6.15 on lattices up to . These calculations allow a more de…
Status of the 0.8 Teraflops Supercomputer at Columbia
I. Arsenin, D. Chen, N. Christ +14
The first stage in the construction of the 0.8 Teraflops Supercomputer at Columbia, a working, two node parallel computer, has been successfully completed. The next stage, a 512 no…
Heavy-light meson decay constants from NRQCD: an analysis of the 1/M corrections
S. Collins, U. M. Heller, J. Sloan +3
We present {\it preliminary} results for the decay constants of heavy-light mesons using NRQCD heavy and tadpole improved Clover light quarks. A comparison is made with data obtain…
Two-flavor staggered-fermion thermodynamics at
C. Bernard, T. Blum, C. DeTar +7
We present new results in an ongoing study of the nature of the high temperature crossover in QCD with two light fermion flavors. These results are obtained with the conventional s…
quenched and unquenched
C. Bernard, T. Blum, A. De +12
Results for , , , , and their ratios are presented. High statistics quenched runs at , , , and , plus a run still in progress at…
Tuning the generalized Hybrid Monte Carlo algorithm
A D Kennedy, Robert Edwards, Hidetoshi Mino +1
We discuss the analytic computation of autocorrelation functions for the generalized Hybrid Monte Carlo algorithm applied to free field theory and compare the results with numerica…
Comparison between Theoretical Four-Loop Predictions and Monte Carlo Calculations in the Two-Dimensional -Vector Model for
Sergio Caracciolo, Robert G. Edwards, Tereza Mendes +2
We have computed the four-loop contribution to the beta-function and to the anomalous dimension of the field for the two-dimensional lattice -vector model. This allows the deter…

Urs M. Heller
We present further evidence for the bulk nature of the phase transition line in the fundamental--adjoint action plane of SU(3) lattice gauge theory. Computing the string tension an…

Urs M. Heller
We present further evidence for the bulk nature of the phase transition line in the fundamental--adjoint action plane of SU(3) lattice gauge theory. Computing the string tension an…
Precision Charmonium Spectroscopy From Lattice QCD
C. T. H. Davies, K. Hornbostel, G. P. Lepage +3
We present results for Charmonium spectroscopy using Non-Relativistic QCD (NRQCD). For the NRQCD action the leading order spin-dependent and next to leading order spin-independent…
The Gluon Propagator at High Temperature
Urs M. Heller, ; Frithjof Karsch, Joern Rank
We study the gluon propagator in Landau gauge in the deconfined phase of gauge theory. From the long-distance behaviour of correlation functions of temporal and spatial com…
Is There Quantum Gravity in Two Dimensions?
Wolfgang Beirl, Bernd A. Berg
A hybrid model which allows to interpolate between the (original) Regge approach and dynamical triangulations is introduced. The gained flexibility in the measure is exploited to s…
Multicanonical Recursions
Bernd A. Berg
The problem of calculating multicanonical parameters recursively is discussed. I describe in detail a computational implementation which has worked reasonably well in practice.
SU(2) Lattice Gauge Theory with Logarithmic Action: Scaling and Universality
Urs M. Heller
We investigate a version of SU(2) lattice gauge theory with a logarithmic action. The model is found to exhibit confinement, contrary to previous claims in the literature. Comparin…
