1 DeTar, CarletonFinite-size and quark mass effects on the QCD spectrum with two flavorsWe have carried out spectrum calculations with two flavors of dynamical Kogut-Susskind quarks on four lattice sizes from 83X24 to 163 X 24 at couplings that correspond to chiral symmetry restoration for a lattice with six time slices. We estimate that the linear spatial sizes of the lattices range f...Kogut-Susskind quarks; Hadron mass; Pion mass1993-11
2 DeTar, CarletonExotic hybrid mesons with light quarksHybrid mesons, made from a quark, an antiquark and gluons, can have quantum numbers inaccessible to conventional quark-antiquark states. Confirmation of such states would give information on the role of "dynamical" color in low energy QCD. We present preliminary results for hybrid meson masses using...Hybrid mesons; Kogut-Susskind quarks; Wilson quarks1997-02
3 DeTar, CarletonQCD thermodynamics with two flavors at Nt=6The first results of numerical simulations of quantum chromodynamics on the Intel iPSC/860 parallel processor are presented. We performed calculations with two flavors of Kogut-Susskind quarks at Nt = 6 with masses of 0.15T and 0.075T (0.025 and 0.0125 in lattice units) in order to locate the crosso...Kogut-Susskind quarks; Crossover temperature; Chiral symmetry; Polyakov loop; Phase transitions1992-05
4 DeTar, CarletonImproving flavor symmetry in the Kogut-Susskind hadron spectrumWe study the effect of modifying the coupling of Kogut-Susskind quarks to the gauge field by replacing the link matrix in the quark action by a ‘‘fat link,'' or sum of link plus three-link paths. Flavor symmetry breaking, determined by the mass difference between the Goldstone and non-Goldston...Kogut-Susskind quarks; Flavor symmetry; Fat links1997-02
5 DeTar, CarletonLight quark spectrum with improved gauge and fermion actionsWe 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 quarks1998-04
6 DeTar, CarletonLight 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 extrapolation1998-01
7 DeTar, CarletonHeavy-light decay constants with dynamical gauge configurations and Wilson or improved valence quark actionsWe describe a calculation of heavy-light decay constants including virtual quark loop effects. We have generated dynamical gauge configurations at three _x000C_ values using two flavors of Kogut-Susskind quarks with a range of masses. These are analyzed with a Wilson valence quark action. Prelimin...Decay constants; Kogut-Susskind quarks; Wilson quarks; Fat-clover valence quarks2000-04
8 DeTar, CarletonHeavy-light decay constants - MILC results with the Wilson actionWe 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 extrapolation1998-01
