Study of e+e− → γϕJ/ψ from $$ \sqrt{s} $$ = 4.600 to 4.951 GeV
Study of e+e− → γϕJ/ψ from $$ \sqrt{s} $$ = 4.600 to 4.951 GeV
A bstract Using data samples with an integrated luminosity of 6 . 4 fb − 1 collected by the BESIII detector operating at the BEPCII storage ring, the process of e + e − → γϕJ/ψ is studied. The processes of e + e − → ϕχ c 1 , …
