Light meson spectroscopy at BESIII

The BESIII collaboration has collected a sample of 1.311 billion J/ψ events since 2009. In this talk, we will introduce four recent analyses on light meson spec-troscopy at BESIII, including two studies on the X(1835) and two partial wave analyses that are related to searching for and studying glueball candidates

Determination of the number of ψ(3686)\psi(3686) events at BESIII

The numbers of ψ(3686) events accumulated by the BESIII detector for the data taken during 2009 and 2012 are determined to be and , respectively, by counting inclusive hadronic events, where the uncertainties are systematic and the statistical uncertainties are negligible. The number of events for the sample taken in 2009 is consistent with that of the previous measurement. The total number of ψ(3686) events for the two data taking periods is
