The Born cross sections for e(+)e(-) -> 2(p (p) over bar) are measured, and no significant structure is observed in the lineshape. The baryon pair (pp and (p) over bar(p) over bar) invariant mass spectra are consistent with phase space, therefore no hexaquark or di-baryon state is found.eninfo:eu-repo/semantics/openAccessArticle2-s2.0-8510310725610.1103/PhysRevD.103.0520035Q1103Q1WOS:000648528200001
