Measurement of the branching fraction and charge asymmetry of the decay B+ -> D+ D0bar and search for B0 -> D0 D0bar

Belle Collaboration

We report an improved measurement of the B+ -> D+ D0bar and B0 -> D0 D0bar decays based on 657 10^6 BBar events collected with the Belle detector at KEKB. We measure the branching…

Observation of the decay $B^{0} \to J / ψ η$

M. -C. Chang

We report the first observation of $B^{0} \to J / ψ η$ decay. These results are obtained from a data sample that contains 449 million $B B ˉ$ pairs accumulated at the $Υ (4 S)$ resonan…

Search for the Theta(1540)+ pentaquark using kaon secondary interactions at Belle

The Belle Collaboration, K. Abe

Using kaon secondary interactions in the material of the Belle detector, we search for both inclusive and exclusive production of the Theta(1540)+. We set an upper limit of 2.5% at…
