N2 - The process e+e-→φη′ has been studied for the first time in detail using data sample collected with the BESIII detector at the BEPCII collider at center of mass energies from 2.05 to 3.08 GeV.

If the observed structure is identified with the φ(2170), then the ratio of partial width between the φη′ by BESIII and φη by BABAR is (ℬφηRΓeeR)/(ℬφη′RΓeeR)=0.23±0.10(stat)±0.18(syst), which is smaller than the prediction of the ss¯g hybrid models by several orders of magnitude.
