 | DeTar, Carleton | f B for various actions: approaching the continuum limit with dynamical fermions | We present results for pseudoscalar decay constants of heavy-light mesons using both quenched and Nf = 2 dynamical fermion configurations. A variety of fermion actions is investigated: Wilson, nonperturbative clover, and fat-link clover. For heavy quarks the Fermilab formalism is applied. In the q... | Decay constants; Wilson fermions | 2001-03 |

 | DeTar, Carleton | Zero temperature string breaking with staggered quarks | 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. In an extension of work reported ... | Flux tube; String breaking; Wilson loop; Staggered quarks | 2001-03 |
