Description
pp-bar mass threshold enhancement is studied using the data samples of J/ψ and ψ' collected with BESIII detector in 2009. The enhancement is evident in J/ψ radiative decay, which is consistent with BESII result. No significant narrow enhancement is observed in ψ' radiative decay. The study of J/ψ→γπ+π-η' is also presented, it is also consistent with BESII result, which shows that the X(1835) is confirmed at BESIII.
