Measurement of the time-dependent CP-violating asymmetry in BO→KSOπOγ decays

Aurelio Bay, Sun Hee Kim, Tagir Aushev, Stewart Cole, Sanjeev Kumar, Jing Li

We present a new measurement of CP-violation parameters in B0→KS0π0γ decay based on a sample of 275×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One of the B mesons is fully reconstruct ...

Measurement of the wrong-sign decays D0→K+π-π0 and D0→K+π-π+π-, and search for CP violation

Aurelio Bay, Sun Hee Kim, Tagir Aushev, Jing Li

Using 281fb-1 of data from the Belle experiment recorded at or near the Υ(4S) resonance, we have measured the rates of the "wrong-sign" decays D0→K+π-π0 and D0→K+π-π+π- relative to those of the Cabibbo-favored decays D0→K-π+π0 and D0→K-π+π+π-. These wrong- ...

Observation of B̄0 → D0η′ and B̄0 → D*0η′

Sun Hee Kim, Tagir Aushev, Stewart Cole, Jing Li

We report the observation of B̄0 → D 0η′ and the first observation of B̄0 → D*0η′, using 140 fb-1 of data collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. We find the branching fractions to be B(B̄0 → D0 ...

Branching fraction, polarization and CP-violating asymmetries in B 0→D+D- decays

Aurelio Bay, Olivier Schneider, Sun Hee Kim, Tagir Aushev, Mingkui Wang, Chao Wang, Vladislav Balagura, Lei Zhang, Ji Hyun Kim, Jing Li

We present measurements of the branching fraction, the polarization parameters and CP-violating asymmetries in B0→D*+D *- decays using a 140 fb-1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collid ...

Observation of B0→π0π0

Aurelio Bay, Sun Hee Kim, Tagir Aushev, Sanjeev Kumar, Ji Hyun Kim, Jing Li

We report the observation of the decay B0→π0π0, using a 253fb-1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB e+e- collider. The measured branching fraction is B(B0→π0π0)= (2.3-0.5-0.3+0.4+0.2)×10-6, with a significance o ...

Measurement of the branching fraction and CP asymmetry in B+ ρ +π0

Aurelio Bay, Tagir Aushev, Sanjeev Kumar, Ji Hyun Kim, Jing Li

We report a measurement of the branching fraction for the decay B + → ρ+π0 based on a 140 fb -1 data sample collected with the Belle detector at the KEKB asymmetric e+e- collider. We measure the branching fraction B(B+ →+π0) = (13.2 ± 2.3(stat)-1.9 +(syst) ...

Observation of the D1(2420)→Dπ+π- decays

Sun Hee Kim, Tagir Aushev, Ji Hyun Kim, Jing Li

We report on the first observation of D10(2420)→D0π-π+ and D1+(2420)→D+π-π+ decays (where the contribution from the dominant known D1→D*π decay mode is excluded) in the B-→D10π- and B̄0→D1+π- decays, respectively. The observation is based on 15.2×107 BB̄ e ...

Measurement of polarization and triple-product correlations in B→K* decays

Sun Hee Kim, Tagir Aushev, Sanjeev Kumar, Jing Li

We present measurements of decay amplitudes and triple-product correlations in B→K* decays based on 253fb-1 of data recorded at the Υ(4S) resonance with the Belle detector at the KEKB e+e- storage ring. The decay amplitudes for the three different helicity ...

Determination of |Vub| from measurements of the inclusive charmless semileptonic partial rates of B mesons using full reconstruction tags

Aurelio Bay, Sun Hee Kim, Stewart Cole, Sanjeev Kumar, Jing Li

We present a measurement of the Cabibbo-Kobayashi-Maskawa matrix element data collected by the Belle detector at the KEKB e+e-asymmetric collider. Events are tagged by fully reconstructing one of the B mesons, produced in pairs from Υ(4S). The signal for b ...
