Helicity amplitude and branching fraction measurement of $χ_{c J} \to Λ Λ ˉ$

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

Utilizing $2712.4 \pm 14.3$ million $ψ (3686)$ events accumulated by the BESIII experiment, we perform a partial wave analysis of $ψ (3686) \to γ χ_{c J} \to γ Λ Λ ˉ$ decay…

Measurement of Born Cross Sections and Effective Form Factors of $e^{+} e^{-} \to Ω^{-} Ω ˉ^{+}$ from $s$ = 3.7 to 4.7 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +635

Using $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 22.7 fb $^{- 1}$ , collected at center-of-mass energies between 3.7 and 4.7 GeV with the BESIII detector at…
