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…

Measurement of the $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ cross section in the vicinity of 3.872 GeV

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

We report a measurement of the cross section for the process $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ around the $X (3872)$ mass in search for the direct formation of $e^{+} e^{-} \to X (3872)$ through the tw…
