| Title |
Heavy-light decay constants with three dynamical flavors |
| Date |
2002-03 |
| Description |
We present preliminary results for the heavy-light leptonic decay constants in the presence of three light dynamical flavors. We generate dynamical configurations with improved staggered and gauge actions and analyze them for heavy-light physics with tadpole improved clover valence quarks. When the scale is set by mp, we find an increase of ≈23% in fB with three dynamical flavors over the quenched case. Discretization errors appear to be small (≤3%) in the quenched case but have not yet been measured in the dynamical case. |
