Search for B^{0}→K^{*0}K[over ¯]^{*0}, B^{0}→K^{*0}K^{*0} and B^{0}→K^{+}π^{-}K^{∓}π^{±} decays

Olivier Schneider, Mingkui Wang, Chao Wang, Tagir Aushev, Vladislav Balagura, Remi Léandre Albert Louvot, Jing Li

We report a search for the decays B-0 -> K*(0)(K) over bar*(0) and B-0 -> KK-0(0) . We also measure other charmless decay modes with K+ pi K--(-)pi(+) and K+pi K--(+)pi(-) final states. The results are obtained from a data sample containing 657 x 10(6) B ...

We search for dimuon decays of a low mass particle in the decays B-0 -> K*X-0 and B-0 -> rho X-0 using a data sample of 657 x 10(6)B (B) over bar events collected with the Belle detector at the KEKB asymmetric- energy e(+)e(-) collider. We find no evidence ...

Precise measurement of hadronic τ-decays with an η meson

Olivier Schneider, Chao Wang, Tagir Aushev, Sun Hee Kim, Remi Léandre Albert Louvot, Xiao Wang

We have studied hadronic τ decay modes involving an η meson using 490 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. The following branching fractions have been measured: B (τ- → K- η ντ) = (1.58 ± 0.05 ± 0.09) ...

Measurement of yCP in D0 meson decays to the KS0K+K- final state

Olivier Schneider, Aurelio Bay, Mingkui Wang, Chao Wang, Tagir Aushev, Vladislav Balagura, Remi Léandre Albert Louvot, Jing Li

We present a measurement of the D-0 - (D) over bar (0) mixing parameter y(CP) using a flavor-untagged sample of D-0 -> (KSK+K-)-K-0 decays. The measurement is based on a 673 fb(-1) data sample recorded with the Belle detector at the KEKB asymmetric-energy ...

We study transitions between Υ states with the emission of charged pions using 604.6fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The measured product branching fraction is B(Υ(4S)→Υ(1S)π+π-)×B(Υ(1S)→μ+μ-)=(2. ...

We report a measurement of the CP-odd fraction and the time-dependent CP violation in B-0 -> D*+D*- decays, using 657x10(6) BB events collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We measure ...
