The dependence of the cross section on root S shows an enhancement around 4.2 GeV. While the shape of the cross section cannot be fully explained with a single psi(4160) or psi(4260) state, a coherent sum of the two states does provide a reasonable description of the data.eninfo:eu-repo/semantics/openAccessArticle2-s2.0-8507853094110.1103/PhysRevD.101.012008Q1WOS:000508453600003
