Evidence of transverse polarization of $Ξ^{0}$ hyperon in $ψ (3686) \to Ξ^{0} Ξ ˉ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +684

Using $(2.712 \pm 0.014) \times 1 0^{9}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, we report an evidence of $Ξ^{0}$ transverse polarization with a sign…

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…

Search for Lepton-number-violating B+->D-l+l'+ Decays

O. Seon, Y. J. Kwon, T. Iijima

We perform the first search for lepton-number-violating B+->D-l+l'+ decays, where l and l' stand for e or mu, using 772 x 10^6 BB-bar pairs accumulated at the Upsilon(4S) resonance…

Observation of $X (3872) \to J / ψ γ$ and search for $X (3872) \to ψ^{'} γ$ in B decays

V. Bhardwaj, K. Trabelsi, J. B. Singh +2

We report a study of $B \to (J / ψ γ) K$ and $B \to (ψ^{'} γ) K$ decay modes using $772 \times 1 0^{6}$ $B B ˉ$ events collected at the Υ(4S)$ resonance with the Belle detector at the KEKB…

Measurement of cross sections of exclusive $e^{+} e^{-} \to V P$ processes at $s = 10.58$ GeV

K. Belous, M. Shapkin

The cross sections for the reactions $e^{+} e^{-} \to ϕ η, ϕ η^{'}, ρ η, ρ η^{'}$ have been measured using a data sample of 516 fb $^{- 1}$ collected with the Belle detector at th…

Observation of candidate exotic mesons containing heavy quarks with Belle

S. -K. Choi

We report the observation of two resonance-like structures in the $π^{+} χ_{c 1}$ invariant mass distribution near 4.1 GeV in exclusive $B \to K π^{+} χ_{c 1}$ decays. A detailed Dalitz-plo…
