$R (3780)$ Resonance Interpreted as the $1^{3} D_{1}$ -Wave Dominant State of Charmonium from Precise Measurements of the Cross Section of $e^{+} e^{-} \to$ Hadrons

M. Ablikim, M. N. Achasov, P. Adlarson +606

We report the precise measurements of the cross section of $e^{+} e^{-} \to$ hadrons at center-of-mass energies from 3.645 to 3.871 GeV. We thereby perform the most precise study…
