Measurements of the observed cross sections for $e^+e^- \to$ light hadrons at $\sqrt{s}=$ 3.773 and 3.650 GeV

TL;DR

This paper reports measurements of the cross sections for 18 light hadron final states produced in electron-positron collisions at energies of 3.773 and 3.650 GeV, using data from the BESII detector.

Contribution

First measurement of these specific cross sections at these energies, providing valuable data for understanding light hadron production in electron-positron annihilation.

Findings

Measured cross sections for 18 light hadron final states.

Provided data at two specific energies near the psi(3770) resonance.

Enhanced understanding of light hadron production mechanisms.

Abstract

Using the data sets of 17.3 pb$^{-1}$ collected at $\sqrt{s}=$ 3.773 GeV and 6.5 pb$^{-1}$ collected at $\sqrt{s}=$ 3.650 GeV with the BESII detector at the BEPC collider, we have measured the observed cross sections for 18 exclusive light hadron final states produced in $e^+e^-$ annihilation at the two energy points.
