Study of the dilepton electromagnetic decays of χcJ(1P)
In this paper, the dilepton electromagnetic decays χ cJ ( 1 P ) → J / ψ e + e - and χ cJ ( 1 P ) → J ψ μ + μ - , where χ cJ denotes χ c 0 , χ c 1 and χ c 2 , are calculated systematically in the improved Bethe–Salpeter method. The numerical results of decay widths and the invariant mass distribution...
