Measurement of the Branching Fraction for the Decay $ψ (3686) \to ϕ K_{S}^{0} K_{S}^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +592

Based on $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decay $ψ (3686) \to ϕ K_{S}^{0} K_{S}^{0}$ is…

Measurement of the $e^{+} e^{-} \to Λ Λ ˉ$ cross section from threshold to 3.00 GeV using events with initial-state radiation

BESIII Collaboration, M. Ablikim, M. N. Achasov +600

Using initial-state radiation events from a total integrated luminosity of 11.957 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 3.773 and 4.258…

Measurement of the total and leptonic decay widths of the $J / ψ$ resonance with an energy scan method at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +566

Using $e^{+} e^{-}$ annihilation data sets collected with the BESIII detector, we measure the cross sections of the processes $e^{+} e^{-} \to e^{+} e^{-}$ and $e^{+} e^{-} \to μ^{+} μ^{-}$ at fifteen cent…
