Abstract

We present recent results from the BES experiment on the observation of the Y(2175) in J/ψϕf0(980)ηJ/\psi\to \phi f_0(980) \eta, and η(2225)\eta(2225) in J/ψγϕϕJ/\psi\to \gamma \phi \phi, and X(1440) in J/ψJ/\psi hadronic decays, together with the new observation of ψ(2S)\psi(2S) radiative decays and hadronic decays into n\ks\ldb+c.c.,\ld\ldbπ0,\ld\ldbηn\ks\ldb+c.c., \ld\ldb\pi^0, \ld\ldb\eta. The effort to search for J/ψJ/\psi decays into γγ\gamma\gamma and invisible decays are also reported.
