Prospects of Xi(1530)(0)(Xi)over-bar(1530)(0) pair production at BESIII

摘要

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 psi(3686) - Xi(1530)(Xi) over bar (1530)(0) is predicted at BESIII with the current 3.08 x 10(6) psi(3686) dataset. The averaged precision of the alpha 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 x 10(9) psi(3686) events taken by BESIII detector in the next few years.
