| 摘 要： | We determine the resonant parameters of the vector states φ(1680) and φ(2170) by performing a combined fit to the e+e-→ηφ cross sections from the threshold to 2.85 GeV measured by the BaBar,Belle,BESⅢ,and CMD-3 experiments.The mass(1678-3+5±7) MeV/c2 and width(156±5±9) MeV are obtained for φ(1680),and the mass(2169±5±6)MeV/c2 and width(96-14+17±9)MeV are obtained for φ(2170).The statistical significance ofφ(2...
