Description
Hadron spectroscopy is one of the most important physics goals of BESIII. Since 2009, BESIII has collected 1.3 10^8 J/psi and 0.410^8 of psi', which are the world's largest data samples of J/psi and psi' from e+e- collision. These data are being used to make a variety of interesting and unique studies of QCD exotics (e.g. gluonic excitations and multiquarks) and light meson decay dynamics. Several recent results on light hadron spectroscopy and light hadron decays will be reported, mostly eta' related, including:
1, amplitude analysis of eta'->3pi
2, study of eta'->gamma pi+ -pi- decays
3, observation of the doubly radiative decay eta' -> gamma gamma pi0
