Measurement of Br(Bbar -> D+l-nubar) and Determination of |Vcb|

Belle Collaboration, K. Abe

We present a measurement of the branching fraction for the semileptonic B decay Bbar -> D+l-nubar, where l- can be either an electron or a muon. We find Gamma(Bbar -> D+l-nubar)= (…

A model prediction for polarized antiquark flavor asymmetry

S. Kumano

Polarized flavor asymmetry Delta u-bar/Delta d-bar is investigated in a meson-cloud model. A polarized nucleon splits into a rho meson and a baryon, then the polarized rho meson in…

Observation of B+ -> chi_c0 K+

Belle Collaboration, K. Abe

Using a sample of B\bar{B}$ pairs collected with the Belle detector at the Y(4S) resonance, we make the first observation of the charged B meson decay to chi_c0 and a…

A Measurement of Lifetime Difference in Meson Decays

Belle Collaboration, K. Abe

We report a measurement of the - mixing parameter using 23.4 fb of data collected near the (4S) resonance with the Belle detector at KEKB. $y_{…

Polarized light-antiquark distributions in a meson-cloud model

S. Kumano, M. Miyama

Flavor asymmetry is investigated in polarized light-antiquark distributions by a meson-cloud model. In particular, rho meson contributions to Delta u-bar - Delta d-bar are calculat…
