Search for the decay $B^{0} \to K^{* 0} τ^{+} τ^{-}$ at the Belle experiment

Belle Collaboration, T. V. Dong, T. Luo +193

This letter presents a search for the rare flavor-changing neutral current process $B^{0} \to K^{* 0} τ^{+} τ^{-}$ using data taken with the Belle detector at the KEKB asym…

Measurement of the branching fraction and time-dependent $C P$ asymmetry for $B^{0} \to J / ψ π^{0}$ decays

Belle Collaboration, B. Pal, A. J. Schwartz +156

We measure the branching fraction and time-dependent $C P$ -violating asymmetry for $B^{0} \to J / ψ π^{0}$ decays using a data sample of 711 $f b^{- 1}$ collected on the $Υ (4 S)$ resonan…

Measurement of Time-dependent $C P$ Asymmetries in $B^{0} \to K_{S}^{0} η γ$ Decays

H. Nakano, A. Ishikawa, K. Sumisawa +187

We report a measurement of time-dependent $C P$ violation parameters in $B^{0} \to K_{S}^{0} η γ$ decays. The study is based on a data sample, containing $772 \times 1 0^{6} B B ˉ$ pai…

First evidence for $cos 2 β > 0$ and resolution of the CKM Unitarity Triangle ambiguity by a time-dependent Dalitz plot analysis of $B^{0} \to D^{(*)} h^{0}$ with $D \to K_{S}^{0} π^{+} π^{-}$ decays

The BaBar, Belle Collaborations, : +422

We present first evidence that the cosine of the CP-violating weak phase $2 β$ is positive, and hence exclude trigonometric multifold solutions of the CKM Unitarity Triangle using a…

Observation of Transverse $Λ/ Λ ˉ$ Hyperon Polarization in $e^{+} e^{-}$ Annihilation at Belle

The Belle Collaboration, A. Abdesselam, I. Adachi +445

We report the first observation of the polarization of $Λ/ Λ ˉ$ hyperons transverse to its production plane in $e^{+} e^{-}$ annihilation. We observe a significant polarization that ri…

Measurement of EPR-type flavour entanglement in Upsilon(4S)->B0 B0bar decays

A. Go, A. Bay

The neutral B-meson pair produced at the Upsilon(4S) should exhibit a non-local correlation of the type discussed by Einstein, Podolski, and Rosen (EPR). We measure this correlatio…

Measurement of the branching fraction and time-dependent CP asymmetry for B0→J/ψπ0 decays

Measurement of Time-dependent CP Asymmetries in B0→KS0​ηγ Decays

First evidence for cos2β>0 and resolution of the CKM Unitarity Triangle ambiguity by a time-dependent Dalitz plot analysis of B0→D(∗)h0 with D→KS0​π+π− decays
