Evidence for B- -> tau- nu_tau-bar with a Hadronic Tagging Method Using the Full Data Sample of Belle

Belle Collaboration, K. Hara, Y. Horii +179

We measure the branching fraction of B- -> tau- nu_tau-bar using the full Upsilon(4S) data sample containing 772*10^6 BBbar pairs collected with the Belle detector at the KEKB asym…

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…

First observation of $B_{s}^{0} \to J / ψ η$ and $B_{s}^{0} \to J / ψ η^{'}$

Jin Li

We report first observations of $B_{s}^{0} \to J / ψ η$ and $B_{s}^{0} \to J / ψ η^{'}$ . The results are obtained from 121.4 fb^{-1} of data collected at the $Υ (5 S)$ resonance with the Belle detector…

Precise measurement of the CP violation parameter sin2phi_1 in B0-->(c\bar c)K0 decays

Belle Collaboration, I. Adachi, H. Aihara +173

We present a precise measurement of the CP violation parameter sin2phi_1 and the direct CP violation parameter A_f using the final data sample of 772x10^6 B\bar B pairs collected a…
