The measured Born cross section of e(+)e(-) -> phi eta is found to be consistent with BABAR measurements, but with improved precision. A resonant structure around 2.175 GeV is observed with a significance of 6.9 sigma with mass (21635 +/- 6.2 +/- 3.0) MeV/c(2) and width (31.1(-11.6)(+21.1) +/- 1.1) MeV, where the first uncertainties are statistical and the second are systematic.eninfo:eu-repo/semantics/openAccessStateY(2175)Article2-s2.0-8511435168310.1103/PhysRevD.104.0320073Q1104Q1WOS:000686913600003
