Precise measurement of the \(e^+e^-\to D_s^+D_s^-\) cross sections at center-of-mass energies from threshold to 4.95 GeV

By Besiii Collaboration and others
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,... Show more
