The process $e^+e^-\rightarrow p\overline{p}\pi^0$ has been studied by analyzing data collected at $\sqrt{s}=3.773$ GeV, at $\sqrt{s}=3.650$ GeV, and during a $\psi(3770)$ line shape scan with the BESIII detector at the BEPCII collider. The…

Using $e^+e^-$ collision data corresponding to a total integrated luminosity of 22.7 fb$^{-1}$, collected at center-of-mass energies between 3.7 and 4.7 GeV with the BESIII detector, we present a measurement of energy-dependent cross…

Existing data on the $e^+e^-\to K^+K^-$ cross section at the center-of-mass energy above 2.6 GeV are fitted with a sum of $\psi(3770)$ resonant and continuum contributions. Two solutions for the resonance production cross section are found…

By using the cross sections of e^+e^- \to p\bar{p}{\pi}^0 measured at the center-of-mass energies from 3.65 to 4.60 GeV, we find that the line shape well agrees with pure continuum production parametrized by a power law function and the…

Several intermediate states of the reaction channels $e^{+}e^{-} \rightarrow \pi^{+} \pi^{-} D^{0} \bar{D}^{0}$ and $e^{+}e^{-} \rightarrow \pi^{+} \pi^{-} D^{+}D^{-}$ are studied using the data samples collected with the BESIII detector at…

We measure the cross section for e^+e^- -> \psi(3770) -> hadrons at Ecm=3773 MeV to be (6.38+-0.08^{+0.41}_{-0.30}) nb using the CLEO detector at the CESR e^+e^- collider. The difference between this and the e^+e^- -> \psi(3770) -> DD-bar…

Methods for extracting the $\psi(3770)\to e^+e^-$ decay width from the data on the reaction cross section $e^+e^-\to D\bar D$ are discussed. Attention is drawn to the absence of the generally accepted method for determining…

Using the data samples collected in the energy range from 3.773 to 4.600 GeV with the BESIII detector at the BEPCII collider, we measure the dressed cross sections as a function of center-of-mass energy for $e^+e^-\rightarrow…

Using $e^+e^-$ collision data, corresponding to an integrated luminosity of $892\,\rm pb^{-1}$ collected at center-of-mass energies from 4.84 to 4.95\,GeV with the BESIII detector, we search for the process $e^+e^-\to K^+ K^- \psi(3770)$ by…
