Studies of B0-B0bar Mixing Properties with Inclusive Dilepton Events

N. C. Hastings

We report a precise determination of the B0-B0bar mixing parameter Delta-m_d based on the time evolution of same-sign and opposite-sign dilepton yields in Upsilon(4S) decays. Data…

Study of Exclusive B decays to Charmed Baryons

N. Gabyshev, H. Kichimi, Belle Collaboration

Using 29.1fb-1 of data accumulated at the Upsilon(4S) with the Belle detector at KEKB, we have studied the decay modes B0bar->Lambda_c+ pbar pi+pi-, B- -> Lambda_c+ pbar pi-, and B…

Observation of Ds+ K- and evidence for Ds+ pi- final states in neutral B decays

P. Krokovny, The Belle Collaboration

We report the first observation of a B meson decay that is not accessible by a direct spectator process. The channel B0bar -> Ds+ K- is found in a sample of 85 timse 10^6 B Bbar ev…

Observation of Double cc bar Production in e+ e- Annihilation at sqrt{s} ~ 10.6 GeV

The Belle Collaboration, K. Abe

We report the observation of prompt J/psi via double ccbar production from the e+e- continuum. In this process one ccbar pair fragments into a J/psi meson while the remaining pair…

Precise Measurement of B Meson Lifetimes with Hadronic Decay Final States

Belle collaboration, K. Abe

The lifetimes of the B0bar and B- mesons are extracted from 29.1/fb of data collected with the Belle detector at the KEK B-factory. A fit to the decay length differences of neutral…

Observation of chi_c2 Production in B-meson Decay

Belle Collaboration

We report the first observation of chi_c2 production in B-meson decays. We find an inclusive B -> chi_c2 X branching fraction of (1.80^{+0.23}_{-0.28}+/- 0.26) 10^-3. The data set,…
