Observation of the Exotic State $I ¨ _{1} (1600)$ in $I ¨ (2 S) \to I^^{3} I ¨ _{c 1}, I ¨ _{c 1} \to I ¨ ^{+} I ¨ ^{-} I^\cdot^{'}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +750

A partial wave analysis of the process $I ¨ (2 S) \to I^^{3} I ¨ _{c 1}, I ¨ _{c 1} \to I ¨ ^{+} I ¨ ^{-} I^\cdot^{'}$ is performed using $(2712.4 \pm 14.3) \times 1 0^{6}$ $I ¨ (2 S)$ events collecte…

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…
