Cross section measurement of e+ e− → f1(1285)π+ π− at center-of-mass energies between 3.808 and 4.951 GeV

2025

Abstract

Using data samples collected by the BESIII detector located at the Beijing Electron Positron Collider, the cross sections of the process e+e− → f1(1285)π+π− are measured at 45 center-of-mass energies from 3.808 to 4.951 GeV. An investigation on the energy-dependent cross section is performed, and no significant structure is observed.
