dc.description.abstract | By analyzing a data set of 2.92 fb⁻¹ of e⁺e⁻ collision data taken at √s̅ = 3.773 GeV and 106.41 x 10⁻⁶ ψ3686) decays taken at √s̅ = 3.686 GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the partial decay width for ψ3770) → γχ(c0) to be B(ψ(3770) → γχ(c0)) = (6.88 ± 0.28 ± 0.67) x 10⁻³ and Γ[ψ(3770) → γχ(c0)] = (187 ± 8 ± 19) keV, respectively. These are the most precise measurements to date. | en_US |
