Strong and electromagnetic amplitudes, direct $C P$ and isospin asymmetries in the decays $J / ψ \to K_{S}^{0} K^{+} π^{-} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

Using $e^{+} e^{-}$ annihilation data collected at 26 center-of-mass energy points between 3000.00 and $3119.88 MeV$ with the BESIII detector, corresponding to a total integrated…

Observation of a Doubly-strange Hyperon $Ξ (1720)$ in $J / ψ \to K^{-} Σ^{0} Ξ ˉ^{+} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +758

Based on a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector at BEPCII, we report the first observation of the decay $J/ψ\rightarrow K^- Σ^0 \b…

Search for a massless particle beyond the Standard Model in the $Ξ^{0} \to Λ + invisible$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +765

A search for a massless beyond-standard-model particle is performed in the decay $Ξ^{0} \to Λ + invisible$ using $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with…

First measurement of the $C P$ -violating phase in $B_{s}^{0} \to J / ψ (\to e^{+} e^{-}) ϕ$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +954

A flavour-tagged time-dependent angular analysis of $B_{s}^{0} \to J / ψ ϕ$ decays is presented where the $J / ψ$ meson is reconstructed through its decay to an $e^{+} e^{-}$ pair. The analysis u…
