Resumen

Utilizing data samples of electron-positron collisions recorded with the BESIII detector at the center of mass energy of 3.773 GeV, corresponding to an integrated luminosity of 20.28 fb⁻¹, we report the first search for the CP forbidden process e⁺e⁻ → ψ(3773) → D⁰D⁰ → (K⁰_Sπ⁰)(K⁰_Sπ⁰). No significant signal is observed.We set the upper limit on the observed cross section to be 7.37 fb, and the upper limit on the joint branching fraction of the C-odd correlated neutral D pair B[(D⁰D⁰)_C-odd → (K⁰_Sπ⁰)(K⁰_Sπ⁰)] < 2.04 × 10⁻⁶ at the 90% confidence level.
