Combined fit to BaBar and Belle Data on e+e- to phi pi+ pi- and phi f0(980)

A combined fit is performed to the BaBar and Belle measurements of the $\EE \to \phi \pi^+ \pi^-$and$\phi \fzero$ cross sections for center-of-mass energy between threshold and 3.0 GeV. The resonance parameters of the $\varphi (1680)$ and Y(2175) are determined. The mass is $(1681_{-12}^{+10})$ MeV/$c^2$ and the width is $(221_{-24}^{+34})$ MeV/$c^2$ for the $\varphi (1680)$, and the mass is $(2117_{-49}^{+59})$ MeV/$c^2$ and the width is $(164_{-80}^{+69})$ MeV/$c^2$ for the Y(2175). These information will shed light on the understanding of the nature of the excited $\varphi$ and $Y$ states observed in $\text{EE}$ annihilation.
