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…

$Z = 14$ Magicity Revealed by the Mass of the Proton Dripline Nucleus $^{22}$ Si

Y. M. Xing, Y. F. Luo, Y. H. Zhang +36

Using the $B ρ$ -defined isochronous mass spectrometry technique, we conducted the first mass measurement of the proton dripline nucleus $^{22}$ Si. We confirm that $^{22}$ Si is bound…

Observation of the $W$ -annihilation process $D_{s}^{+} \to ω ρ^{+}$ and measurement of $D_{s}^{+} \to ϕ ρ^{+}$ in $D_{s}^{+} \to π^{+} π^{+} π^{-} π^{0} π^{0}$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

We present the first amplitude analysis and branching fraction measurement of the decay $D_{s}^{+} \to π^{+} π^{+} π^{-} π^{0} π^{0}$ , using $e^{+} e^{-}$ collision data collected with the BESIII detector…
