Study of the B→X(3872)(→D*0D̄0)K decay

Jean Wicht, Aurelio Bay, Remi Léandre Albert Louvot, Nicolas Zwahlen, Olivier Schneider, Tagir Aushev, Chao Wang, Vladislav Balagura, Ji Hyun Kim, Jing Li

We present a study of B→X(3872)K with X(3872) decaying to D0D̄0 using a sample of 657×106 BB̄ pairs recorded at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. Both D0→D0γ and D*0→D0π0 decay modes are used. We fin ...

Measurement of B→Ds(*)Kπ branching fractions

Aurelio Bay, Remi Léandre Albert Louvot, Nicolas Zwahlen, Olivier Schneider, Mingkui Wang, Chao Wang, Vladislav Balagura, Ji Hyun Kim

We report a measurement of the exclusive B+ meson decay to the D-s(()K-)(+)pi(+) final state using 657 x 10(6) B (B) over bar pairs collected at the gamma(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We use D-s - ...

Evidence of time-dependent CP violation in the decay B^{0}→D^{+}D^{-}

Jean Wicht, Aurelio Bay, Remi Léandre Albert Louvot, Nicolas Zwahlen, Olivier Schneider, Tagir Aushev, Chao Wang, Vladislav Balagura, Jing Li

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 ...

Study of the B -> X(3872)K -> D*°-D°K decay at Belle

Nicolas Zwahlen

Recently, many unexpected new particles were discovered with masses around 4 GeV/c2. They are collectively called XYΖ mesons and while some of them have been identified as charmonium states, many others have properties that don't fit into the quark-antiqua ...

Measurement of the decay Bs0→Ds-π+ and evidence for Bs0→Ds K± in e+e- annihilation at s 10.87GeV

Jean Wicht, Aurelio Bay, Remi Léandre Albert Louvot, Nicolas Zwahlen, Olivier Schneider, Sun Hee Kim, Tagir Aushev, Chao Wang, Vladislav Balagura, Xiao Wang, Jing Li

We have studied Bs0→Ds-π+ and Bs0→Ds K± decays using 23.6fb-1 of data collected at the Υ(5S) resonance with the Belle detector at the KEKB e+e- collider. This highly pure Bs0→Ds-π+ sample is used to measure the branching fraction, B(Bs0→Ds-π+)=[3.67-0.33+0 ...
