Study of the dilepton electromagnetic decays of $$\chi _{cJ}(1P)$$ χcJ(1P)
Abstract In this paper, the dilepton electromagnetic decays $$\chi _{cJ}(1P) \rightarrow J/\psi e^+e^-$$ χcJ(1P)→J/ψe+e- and $$\chi _{cJ}(1P) \rightarrow J\psi \mu ^+\mu ^-$$ χcJ(1P)→Jψμ+μ- , where $$\chi _{cJ}$$ χcJ denotes $$\chi _{c0}$$ χc0 , $$\chi _{c1}$$ χc1 and $$\chi _{c2}$$ χc2 , are calcul...
