Study of the radiative decay J/ψ → ηc + γ in light cone sum rules
At present, there are many experimental and theoretical results for J/ψ→ηc+γ process, while the results are inconsistent based on different methods and considerations. In this paper, the light cone sum rules method is used in studying the radiative decay J/ψ→ηc+γ. We give the transition form factor...
