Description

At BESIII, the lineshapes of e+e- ->phi eta', phi eta, KK, omega pi0, eta pipi, omega pipi are measured
from 2.0 to 3.08 GeV, where resonant structures are observed in these processes. Multiple lineshapes of
intermediate state are obtained by a partial wave analysis of e+e- ->K+ K- pi0 pi0, K+K- pi0 and the
structures observed provide essential input to understand the nature of phi2170. These results provide
important information for light flavor vector mesons i.e. excited rho, omega and phi, for energy regions above 2 GeV.
