The anti-B --> D* lepton anti-neutrino form factor at zero recoil and the determination of V(cb)
We summarize our lattice QCD study of the form factor at zero recoil in the
decay anti-B --> D* lepton anti-neutrino. After careful consideration of all
sources of systematic uncertainty, we find,
h_A1(1) = 0.913(+0.024-0.017)(+0.017-0.030), where the first uncertainty is
from statistics and fitting while the second combined uncertainty is from all
other systematic effects.Comment: Lattice2001(HeavyQuark); 3 pages, 2 eps figures, espcrc2.st
