Measurement of D0 -> pilnu (Klnu) Form Factors and Absolute Branching Fractions

L. Widhalm

Using a 282 1/fb data sample collected by the Belle experiment at the KEKB e+e- collider, we study D0 decays to K-l+nu and pi-l+nu final states. The D0 flavor and momentum are tagg…

Evidence of the Purely Leptonic Decay B- --> tau- nu_tau-bar

K. Ikado

We present the first evidence of the decay B- --> tau- nu_tau-bar using 414 fb^-1 of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-ener…

Observation of Large CP Violation and Evidence for Direct CP Violation in B0-->pi+pi- Decays

K. Abe

We report the first observation of CP-violating asymmetries in B0 --> pi+pi- decays based on a 140 fb-1 data sample collected at the Upsilon(4S) resonance with the Belle detector a…

Measurement of |V_ub| using inclusive B -> X_u l nu decays with a novel X_u-reconstruction method

H. Kakuno

We report the measurement of an inclusive partial branching fraction for charmless semileptonic B decay and the extraction of |V_ub|. Candidates for B -> X_u l nu are identified wi…

Study of Time-Dependent CP-Violating Asymmetries in b->sq q Decays

K. Abe

We present a measurement of CP-violation parameters in the b->sq q penguin transitions (q=s,u,d) based on a 78/fb data sample collected at the Y(4S) resonance with the Belle detect…

Study of Decays

The Belle Collaboration, A. Satpathy

We report on a study of decays using 29.1 fb of annihilation data recorded at the resonance with the Belle detector…
