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…

Observation of $D_{s}^{+} \to a_{0} (980)^{+} f_{0} (500)$ in the Amplitude Analysis of $D_{s}^{+} \to I ¨ ^{+} I ¨ ^{0} I ¨ ^{0} I^\cdot$

BESIII Collaboration, M. Ablikim, M. N. Achasov +716

We report the first observation of the decay $D_{s}^{+} \to I ¨ ^{+} I ¨ ^{0} I ¨ ^{0} I^\cdot$ in a data set corresponding to an integrated luminosity of 7.33 fb $^{- 1}$ , collected in $e^{+} e^{-}$ collisions…

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…
