1 DeTar, CarletonAssorted weak matrix elements involving the bottom quarkAs part of a larger project to estimate the fB decay constant, we are recalculating fstatic B using a variational smearing method in an effort to improve accuracy. Preliminary results for the static BB parameter and HQET two point functions are also presented.Bottom quark; Decay constants; HQET; Effective field theory1997-02
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, CarletonFinite temperature lattice QCD with clover fermionsWe report on our simulation of finite temperature lattice QCD with two flavors of O(a) Symanzik-improved fermions and O(a2) Symanzik-improved glue. Our thermodynamic simulations were performed on an 83 × 4 lattice, and we have performed complementary zero temperature simulations on an 83 × 16 la...Wilson quarks; Clover fermions1997-02
4 DeTar, CarletonRecent MILC spectrum results*We report on results from three spectrum calculations with staggered quarks: 1) a quenched calculation with the standard action for the gluons and quarks; 2) a quenched calculation with improved actions for both the gluons and quarks; and 3) a calculation with two flavors of dynamical quarks using...Staggered quarks; Hadron spectrum1997-02
5 DeTar, CarletonThermodynamics for two flavor QCD*We conclude our analysis of the Nt = 6 equation of state (EOS) for two flavor QCD, first described at last year's conference. We have obtained new runs at amq = 0.025 and improved runs at amq = 0.0125. The results are extrapolated to mq = 0, and we extract the speed of sound as well. We also present...Phase transitions; Quark-gluon plasma; Chiral symmetry1997-02
6 DeTar, CarletonUpdate on fBWe describe the current status of the MILC collaboration computation of fB, fBs , fD, fDs and their ratios. Progress over the past year includes: better statistics and plateaus at _x000C_β = 6.52 (quenched), β_x000C_ = 5.6 (NF = 2) and β_x000C_ = 5.445 (NF = 2), new runs with a wide range of dyn...Decay constants; Wilson quarks1997-02
