Measurements of the continuum $R_{\mathrm{uds}}$ and $R$ values in $e^{+}{e}^{-}$ annihilation in the energy region between 3.650 and 3.872 GeV

M. Ablikim et al

We report measurents of the continuum $R_{\mathrm{uds}}$ near the center-of-mass energy of 3.70 GeV, the $R_{\mathrm{uds}(\mathrm{c})+\psi (3770)}(s)$ and the $R_{\mathrm{had}}(s)$ values in $e^{+}{e}^{-}$ annihi…
