We summarize our lattice QCD study of the form factor at zero recoil in the decay[bar B][yields] D*[ell][bar[nu]]. After careful consideration of all sources of systematic uncertainty, we find, h[sub A[sub 1]](1)= 0.913[sub -17-30][sup+24+17], where the first uncertainty is from statistics and fitting while the second combined uncertainty is from all other systematic effects.

The zero recoil limit of the B[yields]Dl[nu] form factors is calculated on the lattice, which provides a model-independent determination of [vert-bar]V[sub cb][vert-bar]. Considering a ratio of form factors, in which the bulk of statistical and systematic errors cancel, we obtain a precise result both for h[sub +](1) and for h[sub -](1).

We summarize our lattice QCD study of the form factor at zero recoil in the decay {bar B} 2!D*l{bar {nu}}. After careful consideration of all sources of systematic uncertainty, we find, h{sub A1}(1) = 0.913{sub 1}--30{sup +24+17}, where the first uncertainty is from statistics and fitting while the second combined uncertainty is from all other systematic effects.

The authors describe a model independent lattice QCD method for determining the deviation from unity for h{sub A{sub 1}}, the B {r{underscore}arrow} D*l[nu] form factor at zero recoil. They extend the double ratio method previously used to determine the B {r{underscore}arrow} Dl[nu] form factor. The bulk of statistical and systematic errors cancel in the double ratios they consider, yielding form factors which promise to reduce present theoretical uncertainties in the determination of {vert{underscore}bar}V{sub cb}{vert{underscore}bar}. They present results from a prototype calculation at a single lattice spacing corresponding to [beta] = 5.7.

The zero recoil limit of the B2!l[nu] form factors is calculated on the lattice, which provides a model-independent determination of {vert_bar}V{sub cb}{vert_bar}. Considering a ratio of form factors, in which the bulk of statistical and systematic errors cancel, we obtain a precise result both for h+(1) and for h(1).

We present an update of our calculation of the form factor for {bar B} --> D*l{bar {nu}} at zero recoil, with higher statistics and finer lattices. As before, we use the Fermilab action for b and c quarks, the asqtad staggered action for light valence quarks, and the MILC ensembles for gluons and light quarks (Luescher-Weisz married to 2+1 rooted staggered sea quarks). In this update, we have reduced the total uncertainty on F(1) from 2.6% to 1.7%.

We have studied the decay {bar B} → Dl{bar {nu}}, where l = e or [mu]. From a fit to the differential decay rate d[Lambda]/dw we measure the rate normalization F{sub D}(1).
