 | DeTar, Carleton | Heavy-light decay constants using clover valence quarks and three flavors of dynamical improved staggered quarks | Starting in 2001, the MILC Collaboration began a large scale calculation of heavy-light meson decay constants using clover valence quarks on ensembles of three flavor configurations. For the coarse configurations, with a = 0.12 fm, eight combinations of dynamical light and strange quarks have been ... | Decay constants; Clover valence quarks; Staggered quarks | 2005-03 |

 | DeTar, Carleton | Leptonic decay constants fDs and fD in three flavor lattice QCD | We determine the leptonic decay constants fDs and fD in three flavor unquenched lattice QCD. We use O(a2)-improved staggered light quarks and O(a)-improved charm quarks in the Fermilab heavy quark formalism. Our preliminary results, based upon an analysis at a single lattice spacing, are fDs = 263+5... | Decay constants | 2005-03 |

 | DeTar, Carleton | Results for light pseudoscalars from three-flavor simulations | We compute pseudoscalar meson masses and decay constants in partially quenched QCD with three dynamical flavors of improved staggered quarks. Fitting the lattice data to staggered chiral perturbation theory (SX_x001F_PT) forms and extrapolating in quark mass and lattice spacing, we find: frr = 129... | Pseudoscalars; Decay constants; Staggered quarks | 2005-03 |

 | DeTar, Carleton | Semileptonic D → π/K and B → π/D decays in 2+1 flavor lattice QCD | We present results for form factors of semileptonic decays of D and B mesons in 2+1 flavor lattice QCD using the MILC gauge configurations. With an improved staggered action for light quarks, we successfully reduce the systematic error from the chiral extrapolation. The results for D decays are in a... | Semileptonic decay | 2005-03 |

 | DeTar, Carleton | Three flavor QCD at high temperatures | We have continued our study of the phase diagram of high temperature QCD with three flavors of improved staggered quarks. We are performing simulations with three degenerate quarks with masses less than or equal to the strange quark mass ms and with degenerate up and down quarks with masses mu,d le... | Quark number; Polyakov loop | 2005-03 |

 | DeTar, Carleton | Topological susceptibility with three flavors of staggered quarks | As one test of the validity of the staggered-fermion fourth-root determinant trick, we examine the suppression of the topological susceptibility of the QCD vacuum in the limit of small quark mass. The suppression is sensitive to the number of light sea quark flavors. Our study is done in the presenc... | Staggered quarks; Chiral perturbation | 2005-03 |
