Ward Identity of the Vector Current and the Decay Rate of $η_{c} \to γ γ$ in Lattice QCD

Chuan Liu, Yu Meng, Ke-Long Zhang

Using a recently proposed method arXiv:1910.11597 (Yu Meng et al.), we study the two-photon decay rate of $η_{c}$ using two $N_{f} = 2$ twisted mass gauge ensembles with lattice spacings…

A Lattice Study of the Two-photon Decay Widths for Scalar and Pseudo-scalar Charmonium

Ying Chen, Ming Gong, Ning Li +7

In this exploratory study, two photon decay widths of pseudo-scalar ( $η_{c}$ ) and scalar ( $χ_{c 0}$ ) charmonium are computed using two ensembles of $N_{f} = 2$ twisted mass lattice QCD ga…
