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 CP Violation in the Decay $D^{+} \to K_{S}^{0} K^{+}$

B. R. Ko, E. Won, I. Adachi +142

We search for CP violation in the decay $D^{+} \to K_{S}^{0} K^{+}$ using a data sample with an integrated luminosity of 977 fb $^{- 1}$ collected with the Belle detector at the KEKB…

Study of the decays B->D_s1(2536)+ anti-D(*)

T. Aushev

We report a study of the decays B -> D_s1(2536)+ anti-D(*), where anti-D(*) is anti-D0, D- or D*-, using a sample of 657 x 10^6 B anti-B pairs collected at the Upsilon(4S) resonanc…

Observation of $B_{s}^{0} \to J / ψ f_{0} (980)$ and Evidence for $B_{s}^{0} \to J / ψ f_{0} (1370)$

Jin Li

We report the first observation of $B_{s}^{0} \to J / ψ f_{0} (980)$ and first evidence for $B_{s}^{0} \to J / ψ f_{0} (1370)$ , which are CP eigenstate decay modes. These results are obtained from $121.…
