Description:
Author(s): Yi-Bo Yang, Ying Chen, Long-Cheng Gui, Chuan Liu, Yu-Bin Liu, Zhaofeng Liu, Jian-Ping Ma, and Jian-Bo Zhang (CLQCD Collaboration) Properties of 2 -+ charmonium η c 2 are investigated in quenched lattice QCD. The mass of η c 2 is determined to be 3.80(3) GeV, which is close to the mass of D -wave charmonium ψ (3770) and in agreement with quark model predictions. The transition width of η c 2 → γ J / ψ is also obtained with a value of Γ =3.8(9... [Phys. Rev. D 87, 014501] Published Wed Jan 02, 2013
