Özet
Abstract: Based on electron-positron collision data collected with the BESIII detector operating at the Beijing Electron-Positron Collider II storage rings, the value of R?(e+e-?hadrons)/?(e+e-??+?-) is measured at 14 center-of-mass energies from 2.2324 to 3.6710 GeV. The resulting uncertainties are less than 3.0% and are dominated by systematic uncertainties. © 2022 authors. Published by the American Physical Society.
