$\mathcal{R}(3780)$ 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…
