While the excitation spectrum of light-meson, which are composed of up and down quarks, is already mapped out rather well, the strange-meson spectrum still holds many surprises that we need to discovered. At the COMPASS experiment at CERN, we study the spectrum of strange mesons using a negative kaon beam. The flagship channel is the decay to the $K^−\pi^−\pi^+$ final state, for which COMPASS...

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. ...
