Description:
Author(s): Ying Chen, De-Chuan Du, Bao-Zhong Guo, Ning Li, Chuan Liu, Hang Liu, Yu-Bin Liu, Jian-Ping Ma, Xiang-Fei Meng, Zhi-Yuan Niu, and Jian-Bo Zhang (CLQCD Collaboration) We present an exploratory study for charmonium radiative transitions: J / ψ → η c γ , χ c 0 → J / Ψ γ , and h c → η c γ using N f =2 twisted-mass lattice QCD gauge configurations. The single-quark vector form factors for η c and χ c 0 are also determined. The simulation is performed at a lattice spacing of a =0.067(2) fm an... [Phys. Rev.
