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…

Beam-energy and centrality dependence of direct-photon emission from ultra-relativistic heavy-ion collisions

A. Adare, S. Afanasiev, C. Aidala +669

The PHENIX collaboration presents first measurements of low-momentum ( $0.4 < p_{T} < 3$ GeV/ $c$ ) direct-photon yields from Au $+$ Au collisions at $s_{_{N N}}$ =39 and 62.4 GeV. For b…

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…

Search for the decay B0 -> phi gamma

Belle Collaboration, Z. King, B. Pal +167

We have searched for the decay B0 -> phi gamma using the full Belle data set of 772 x 10^6 BBbar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB e+…
