DeTar, Carleton | Exotic meson spectroscopy from the clover action at β = 5.85 and 6.15* | We repeat our original simulations of the hybrid meson spectrum using the clover action, as a check on lattice artifacts. Our results for the 1−+ masses do not substantially change. We present preliminary results for the wave function of the 1−+ state in Coulomb gauge. | Clover action; Quark spectroscopy | 1999-03 |

DeTar, Carleton | Heavy-light decay constants: conclusions from the Wilson action | We report on the results of a MILC collaboration calculation of fB, fBs , fD, fDs and their ratios. We discuss the most important errors in more detail than we have elsewhere. | Decay constants; Wilson action; Staggered quarks | 1999-03 |

DeTar, Carleton | String breaking in lattice QCD | The separation of a heavy quark and antiquark pair leads to the formation of a tube of flux, or string, which should break in the presence of light quark-antiquark pairs. This expected zero temperature phenomenon has proven elusive in simulations of lattice QCD. We present simulation results that ... | String breaking; Flux tube; Staggered quarks; Wilson loop; Polyakov loop | 1999-03 |

Mattis, Daniel C. | Three-band model of high-Tc superconductivity | We reduce the three-band model of planar CuO2 to a single-band of composite fermions. We obtain hopping parameters teff(Rij), repulsive potentials Ueff and V(Ri j), and the superexchange interactions J(Ri j) necessary for both antiferromagnetism and superconductivity. The ratios of these quantitie... | Copper oxides; Composite fermions; Charge transport; Bloch energies; Superexchange | 1999-03 |
