ABSTRACT
Using the $e^+e^-$ collision data collected with BESIII detector operating at BEPCII collider, center-of-mass energies from threshold to $4.95$~GeV, we present precise measurements of cross sections for process $e^+e^-\to D_s^+D_s^-$ using a single tag method. The resulting section lineshape exhibits several new structures, thereby offering an input coupled channel analysis and model tests, which are critical understand vector charmonium-like states masses between 4 5~GeV.
