Download Recent Results in Semileptonic B Decays with BaBar Book in PDF, ePub and Kindle
In this note, recent results of studies of semileptonic B meson decays from BABAR are discussed and preliminary results given. In particular, a recent measurement of?(B → D{sup (*)}??) and the ratio?(B → D{sup (*)}??)/?(B → D{sup (*)}l?) is presented. For the D* mode, a branching fraction of 1.79 ± 0.13(stat) ± 0.17(syst) is found, with a ratio of 0.325 ± 0.023(stat) ± 0.027(syst). For the D mode, the results are 1.04 ± 0.12(stat) ± 0.14(syst) and 0.456 ± 0.053(stat) ± 0.056(syst), respectively. In addition, a study of B{sub s} production and semileptonic decays using data collected in a center-of-mass energy region above the?(4S) resonance is discussed. The semileptonic branching fraction?(B{sub s} → l?X) is measured to be 9.9{sub -2.1}{sup +2.6}(stat){sub -2.0}{sup +1.3}(syst).

Download Semileptonic B Decays at BABAR. Book in PDF, ePub and Kindle
We present results on semileptonic B decays obtained with the BABAR detector. The large data set accumulated at the PEP-II asymmetric-energy B-Factory allows a new measurement technique, where the hadronic decay of one B meson is fully reconstructed and the semileptonic decay of the recoiling B meson is studied. Traditional analysis techniques of inclusive and exclusive B decays complement this approach with very high statistics data samples. These measurements play an important role in the tests of the description of CP violation in the Standard Model: The determinations of the Cabibbo-Kobayashi-Maskawa matrix elements V[sub cb] and V[sub ub] provide constraints on the unitarity of the CKM triangle. Furthermore, the experimental measurement of parameters of Heavy Quark Effective Theory test the consistency of the theoretical description of semileptonic B decays.

The latest results of exclusive charmless semileptonic decays B → [pi]lv and B → [rho]lv from the BABAR Collaboration are presented. They are based on samples of B{bar B} events recorded on the [Upsilon](4S) resonance. Several different experimental techniques are compared. Measurements of partial branching fractions in intervals of q2, the four-momentum transfer squared, allow a study of the shape of the B → [pi]lv form factor and a comparison with theoretical calculations. The Cabibbo-Kobayashi-Maskawa matrix element.
