Heavy Flavor Physics [bottom, charm, tau]

The Bc meson, composed of two heavy quarks of distinct flavor, provides a very interesting system to study. CDF experiment is the leading contributor to the experimental studies of Bc mesons, with measurements of both production and decay properties. We report amongst other results the measurement of production cross section and lifetime, using semileptonic Bc -> J/psi mu X decays.

328. Production measurements at LHCb with the first data

Heavy Flavor Physics [bottom, charm, tau]

We report on the perspective measurements of inclusive particle production in high-energy pp collisions with data to be collected by the LHCb experiment at CERN's LHC. These include V0 and D meson production studies, which can be based on a minimum bias sample, as well as charmonia production studies, which need a muon-triggered samples. Using reconstructed J/psi -> mu+mu- decays, both the...

70. Branching Fraction Measurements of the decays D0 --> Vector Eta

Heavy Flavor Physics [bottom, charm, tau]

We present preliminary results for branching fraction measurements of the decays D0 --> V eta where V is a phi, omega or K*. We use a high statistics data sample collected with the BaBar detector at the PEP-II asymmetric e+ e- collider at SLAC.

95. A search for the decay B --> l nu gamma

Ms Dana LINDEMANN (McGill University)

Heavy Flavor Physics [bottom, charm, tau]

We present the search for the radiative leptonic decay modes B+ -> e nu gamma and B+ -> mu nu gamma using data collected by the BaBar detector at the PEP-II B-factory. In this analysis, we fully reconstruct the hadronic decay of one of the B mesons from the Upsilon(4S) --> BBbar and then search for evidence of the B+ --> l+ nu gamma decay in the remaining particles...

106. Exclusive semileptonic b->c decays at BaBar and the determination of |Vcb|

Mr Manuel FRANCO SEVILLA (SLAC)

Heavy Flavor Physics [bottom, charm, tau]

We report a measurement of the branching fractions of B -> D** l nu decays based on 417 fb-1 of data collected at the Upsilon (4S) resonance with the BABAR detector at the PEP-II e+e- storage rings. Events are selected by fully reconstructing one of the B mesons in a hadronic decay mode. A fit to the invariant mass differences m(D(*)pi) - m(D(*)) is performed to extract the signal yields...

105. Measurement and interpretation of moments in Decays B -> Xc ell nu

Enrico FELTRESI (INFN Padova)

Heavy Flavor Physics [bottom, charm, tau]

Semileptonic B decays to DXlnu (l = e or mu) are selected by reconstructing D0l and D+l combinations from a sample of 230 million Upsilon(4S) -> BB decays recorded with the BABAR detector at the PEP-II e+e- collider at SLAC. A global fit to these samples in a 3-dimensional space of kinematic variables is used to determine the branching fractions B(B- -> D0 l nu) = (2.34 +/- 0.03 +/-...
