The data were collected using the BESIII detector at the BEPCII collider. An enhancement at root s = 2.232 GeV is observed, very close to the e(+)e(-) -> Lambda(Lambda) over bar production threshold. A similar enhancement at the same c.m. energy is observed in the e(+)e(-) -> phi K+ K- cross section. The energy dependence of the K+ K- K+ K- and phi K+ K- cross sections differs significantly from that of e(+)e(-) -> phi pi(+)pi(-).eninfo:eu-repo/semantics/openAccessPhysicsAstronomy & astrophysicsCharmoniumY(2175)StateArticle0004833493000012-s2.0-850725972741003Astronomy & astrophysicsPhysics, particles & fieldsCharmonium; Deterioration; Mesons
