Search for $B^{0}$ decays to invisible final states at Belle

Belle Collaboration, C. -L. Hsu, P. Chang +154

We report a search for $B^{0}$ decays into invisible final states using a data sample of $657 \times 1 0^{6}$ $B B ˉ$ pairs collected at the $Υ (4 S)$ resonance with the Belle dete…

Measurement of the CP-violation Parameter sin2 $ϕ_{1}$ with a New Tagging Method at the $Υ (5 S)$ Resonance

Belle Collaboration, Y. Sato, H. Yamamoto +160

We report a measurement of the CP-violation parameter sin2 $ϕ_{1}$ at the $Υ (5 S)$ resonance using a new tagging method, called " $B$ - $π$ tagging." In $Υ (5 S)$ decays containing a neutra…
