چکیده
Using the data accumulated in 2002-2004 with the D0 detector in proton-antiproton collisions at the Fermilab Tevatron collider with a center-of-mass energy of 1.96 TeV, the branching fractions of the decays B --> D0(1)(2420)mu+ vmuX and B --> D2(*0)(2460)mu+ vmuX and their ratio have been measured: B(b --> B) x B(B --> D0(1)mu+ vmuX) x B(D0(*0) --> D*- pi+) = [0.087 +/- 0.007(stat) +/- 0.014(syst)]%; B(b --> B) x B(B --> D2(*0) mu+ vmuX) x B(D2(*0) --> D*- pi+) = [0.035 +/- 0.007(stat) +/- 0.008(syst)]% and [B(B --> D2(*0)mu+ vmuX) x B(D2(*0) --> D*- pi+)]/[B(B --> D0(1)mu+ vmuX) x B(D0(1) --> D*- pi+)] = 0.39 +/- 0.09(stat) +/- 0.12 (syst), where the charge conjugated states are always implied.

Review of Exclusive B → D (∗,∗∗) lν Decays – Branching Fractions, Form-factors and |Vcb|
This paper reviews semileptonic decays of B-mesons to states containing charm mesons, i.e., D, D, D and possible non-resonant Dnπ states as well. The paper covers measurement of branching fractions, form-factors and, most importantly, the magnitude of the CKM matrix element Vcb. I will not attempt a comprehensive review, but will concentrate on reasonably fresh results and consider mostly exclu...
متن کاملEffects of final state interaction in B^+_c to D^0 K^+ decay
In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...
متن کاملSemileptonic Branching Fractions of Charged and Neutral B Mesons.
An examination of leptons in Υ(4S) events tagged by reconstructed B decays yields semileptonic branching fractions of b− = (10.1 ± 1.8 ± 1.4)% for charged and b0 = (10.9 ± 0.7 ± 1.1)% for neutral B mesons. This is the first measurement for charged B. Assuming equality of the charged and neutral semileptonic widths, the ratio b−/b0 = 0.93 ± 0.18 ± 0.12 is equivalent to the ratio of lifetimes.

متن کاملInclusive Semileptonic B Decays at BABAR
We present measurements of the inclusive semileptonic branching fractions of charged and neutral B mesons using 20.6 fb−1 of data measured at the Υ (4S) with the BABAR detector. Events are tagged with a fully reconstructed hadronic decay of a B meson. The correlation between the flavor of the tag B meson and the electron charge allows the separation of prompt semileptonic B decays and cascade s...
متن کاملSemileptonic B Meson Decays
We review some of the most important topics in the semileptonic decays of B mesons, with emphasis on recent results from CLEO and LEP. We discuss the current data samples, inclusive and exclusive semileptonic decay branching fractions, and form factor measurements in the context of HQET.
