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

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

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

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

BESIII Collaboration, M. Ablikim, M. N. Achasov +770

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…

Observation of a New Excited $I^£$ State in $I ¨ (3686) \to p ˉ K^{+} I^£^{0} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +681

Using a data sample of $(2712.4 \pm 14.3) \times 1 0^{6} I ¨ (3686)$ events collected with the BESIII detector, a partial-wave analysis of $I ¨ (3686) \to p ˉ K^{+} I^£^{0} + c . c .$ is performed. A…
