“…In order to demonstrate the above theoretical hypothesis, the decays of J/ψ → γηηη ′ are investigated by using the two η ′ decay modes, η ′ → γπ + π − and η ′ → π + π − η. However, no evident signal for the X( 2370) is observed in the ηηη ′ invariant mass distribution [10]. The upper limit of B(J/ψ → γX(2370…”

Light meson spectroscopy plays an important role in understanding the Quantum Chromodynamics in non-perturbative energy region and the decay dynamics of unconventional hadronic states. BESIII has collected the largest J/ψ and ψ ′ data samples in the world, which provides an unprecedented opportunity to study the light meson spectroscopy. The paper presents some highlights on light meson spectroscopy achieved in BESIII, such as search for glueball candidates, studies of the structure near p p threshold and studies of strange quarkonium.

The relative simplicity of the lowest-lying charmonium states can be used as benchmarks to test the QCD and QCD-inspired models, as these states lay in the transition region between perturbative and non-perturbative QCD. While the properties and many decay channels of some charmonium states below the open-charm threshold (such as ℎ or (2 )) are still far from being known, many high-mass charmonium states above the open charm threshold predicted by potential models are not been found yet. Since 2009, BESIII has been scanning and investigating the charmonium spectrum to shed light on the internal structure of charmonium states. Thanks to its unique / ,(2 ) and even large XYZ data sets, BESIII could overcome statistical limitations. Recent results on charmonium decays from BESIII are presented.
