First measurements of the absolute branching fraction of $Λ_{c} (2625)^{+} \to Λ_{c}^{+} π^{+} π^{-}$ and upper limit on $Λ_{c} (2595)^{+} \to Λ_{c}^{+} π^{+} π^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +613

The absolute branching fraction of the decay $Λ_{c} (2625)^{+} \to Λ_{c}^{+} π^{+} π^{-}$ is measured for the first time to be $(50.7 \pm 5. 0_{stat.} \pm 4. 9_{syst.}) %$ with 36…

Observation of structures in the processes $e^{+} e^{-} \to ω χ_{c 1}$ and $ω χ_{c 2}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +619

We present measurements of the Born cross sections for the processes $e^{+} e^{-} \to ω χ_{c 1}$ and $ω χ_{c 2}$ at center-of-mass energies $s$ from 4.308 to 4.951 GeV. The mea…

Observation of $χ_{c J} \to 3 (K^{+} K^{-})$

BESIII Collaboration, M. Ablikim, M. N. Achasov +642

By analyzing $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decay processes $χ_{c J} \to 3 (K^{+} K^{-})$ ( $J = 0, 1, 2$ )…

Study of $e^{+} e^{-} \to η ϕ$ at center-of-mass energies from 3.773 to 4.600 GeV

M. Ablikim, M. N. Achasov, P. Adlarson +610

We present a study of the process $e^{+} e^{-} \to η ϕ$ using data samples collected with the BESIII detector corresponding to an integrated luminosity of 15.03 fb $^{- 1}$ at 23 center-…
