Abstract
The study of the baryon–antibaryon pair production from the charmonium states provides a favorable test and an input for the perturbative quantum chromodynamics calculation. Based on a Monte Carlo study via a single tag baryon strategy, a clear observation of [Formula: see text](3686)[Formula: see text](1530)[Formula: see text](1530)0is predicted at BESIII with the current 3.08[Formula: see text]106[Formula: see text](3686) dataset. The averaged precision of the [Formula: see text] parameters in the decay angular distribution formula is estimated as 0.25, and is not effective to separate the theoretical predictions. It will be an opportunity to distinguish them with 3.0[Formula: see text]109[Formula: see text](3686) events taken by BESIII detector in the next few years.
