| 1 |  | DeTar, Carleton | Critical behavior at the chiral phase transition | It is generally expected that two-flavor QCD undergoes a high temperature chiral symmetry restoring phase transition at zero quark mass, with O(4) critical behavior[1]. Verifying this expectation is important for understanding the phenomenology of the transition and for facilitating an extrapolation... | Phase transitions; Staggered fermions | 1998-04 |
| 2 |  | DeTar, Carleton | Heavy-light decay constants - MILC results with the Wilson action | We present the current status of our ongoing calculations of pseudoscalar meson decay constants for mesons that contain one light and one heavy quark (fB, fBs , fD, fDs ). We are currently generating new gauge configurations that include dynamical quarks and calculating the decay constants. In add... | Decay constants; Wilson action; Kogut-Susskind quarks; Staggered quarks; Chiral extrapolation | 1998-01 |
| 3 |  | DeTar, Carleton | Light hadron spectrum - MILC results with the Kogut-Susskind and Wilson actions* | We present the current status of our ongoing calculations of the light hadron spectrum with both Kogut-Susskind (KS) and Wilson quarks in the valence or quenched approximation. We discuss KS quarks first and find that the chiral extrapolation is potentially the biggest source of systematic error. F... | Staggered quarks; Hadron spectrum; Kogut-Susskind quarks; Wilson quarks; Chiral extrapolation | 1998-01 |
| 4 |  | DeTar, Carleton | Light quark spectrum with improved gauge and fermion actions | We report on a study of the light quark spectrum using an improved gauge action and both Kogut-Susskind and Naik quark actions. We have studied six different lattice spacings, corresponding to plaquette couplings ranging from 6.8 to 7.9, with five to six quark masses per coupling. We compare the t... | Quark spectrum; Kogut-Susskind quarks; Naik quarks | 1998-04 |
| 5 |  | DeTar, Carleton | Update on the hadron spectrum with two flavors of staggered quarks | We present an update on the MILC Collaboration's light hadron spectrum calculation with two flavors of dynamical, staggered quarks. Results are presented for gauge couplings 5.30, 5.415, 5.50 and 5.60, with a range of quark masses for each value of the coupling. We present extrapolations of mN/mp ... | Staggered quarks; Hadron spectrum | 1998-04 |
