Observation of $e^{+} e^{-} \to η ψ (2 S)$ at center-of-mass energies from 4.236 to 4.600 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +505

Using a total of $5.25 fb^{- 1}$ of $e^{+} e^{-}$ collision data with center-of-mass energies from 4.236 to 4.600 GeV, we report the first observation of the process $e^{+}e^{-…

Observation of the first iso-spin Charmonium-like State $Z_{c} (4020)$ }

Qing-Ping Ji, Yu-Ping Guo, Ai-Qiang Guo +2

In this paper, we present a new experimental progress in brief on the recent observation of the charged charmonium-like state Z_c(4020)^{+/-} states and its iso-spin partner Z_c(40…
