Abstract: The decays of J/ψ→nK0SΛ and J/ψ→pK0SΣ+ are studied based on BESIII simulation system BOSS6.5.1.The signalparticles are selected with the help of the particle identification software.Both the selection efficiency and background proportion are obtained,and the J/ψdata taking plan is estimated for the baryon excited states study requirement.

Key words: J/ψ decays, baryon spectrum, Monte Carlo simulation
