Precise measurement of the $e^+e^-\to D_s^+D_s^-$ cross sections at
center-of-mass energies from threshold to 4.95 GeV
Using the $e^+e^-$ collision data collected with the BESIII detector operating at the BEPCII collider, at center-of-mass energies from the threshold to $4.95$~GeV, we present precise measurements of the cross sections for the process $e^+e^-\to D_s^+D_s^-$ using a single tag method. The resulting cross section lineshape exhibits several new structures, …
