Abstract
After the first observation of ϕ(2170) in the process ${e^ + }{e^ - } \to {\gamma _{ISR}}\phi {f_0}(980)$, several theoretical interpretations have been proposed to explain the nature of ϕ(2170). Aspects of ϕ(2170) are still not fully understood until now. Large J/ψ events and energy scan data samples collected by the BESIII detector provide the opportunity to perform the further study to ϕ(2170). In this presentation, $J/\psi \to \eta \phi (2170)$ and ${e^ + }{e^ - } \to \eta \phi (2170)$ are studied to improve the measurements of mass and width of ϕ(2170). e+e− → K+K−, $\phi {K^ + }{K^ - }$ and K+K−K+K− are investigated to search for the new decay mode of ϕ(2170). Those studies would be useful for improving the understanding of the nature of ϕ(2170).
