Book Description
We measure the dependence of {bar B}° → D*e−{bar {nu}}{sub e} on the decay angles and momentum transfer. The data sample consists of ≈ 86 x 106 B{bar B}-pairs accumulated on the?(4S) resonance by the BABAR detector at the asymmetric e+e− collider PEP-II. We specify the three form factors by two ratios R1 and R2, and by a single parameter?2 characterizing the polynomial representing h{sub A1}, the function which describes the momentum-transfer dependence of the form factor A1. We determine R1, R2, and?2 using an unbinned maximum likelihood fit to the full decay distribution. The results are R{sub 1} = 1.396 ± 0.060 ± 0.035 ± 0.027, R2 = 0.885 ± 0.040 ± 0.022 ± 0.013, and?2 = 1.145 ± 0.059 ± 0.030 ± 0.035. The stated uncertainties are the statistical from the data, statistical from the size of the Monte Carlo sample and the systematic uncertainty, respectively. In addition, based on this measurement, we give an updated value for the CKM matrix element.

Book Description
We compute the form factors for the B → Kl+l- semileptonic decay process in lattice QCD using gauge-field ensembles with 2+1 flavors of sea quark, generated by the MILC Collaboration. The ensembles span lattice spacings from 0.12 to 0.045 fm and have multiple sea-quark masses to help control the chiral extrapolation. The asqtad improved staggered action is used for the light valence and sea quarks, and the clover action with the Fermilab interpretation is used for the heavy b quark. We present results for the form factors f+(q2), f0(q2), and fT(q2), where q2 is the momentum transfer, together with a comprehensive examination of systematic errors. Lattice QCD determines the form factors for a limited range of q2, and we use the model-independent z expansion to cover the whole kinematically allowed range. We present our final form-factor results as coefficients of the z expansion and the correlations between them, where the errors on the coefficients include statistical and all systematic uncertainties. Lastly, we use this complete description of the form factors to test QCD predictions of the form factors at high and low q2.
