Multi-channel joint analysis of the exotic charmonium-like state $T_{c c ˉ} (4020)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +692

This paper reports the first multi-channel joint analysis to identify the properties of the exotic charmonium-like state $T_{c c ˉ} (4020)$ via the electron-positron annihilation…

Search for a dark baryon in the $Ξ^{-} \to π^{-} + invisible$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

A search for a dark baryon is performed for the first time in the two-body decay $Ξ^{-} \to π^{-} + invisible$ using $(10.087 \pm 0.044) \times 1 0^{9}$ $J / ψ$ events collected at…
