Multiquark resonances are undoubtedly experimentally observed. The number of states and
the amount of details on their properties have been growing over the years. It is very recent …

In the past decade many charmonium-like states were observed experimentally. Especially
those charged charmonium-like Z c states and bottomonium-like Z b states cannot be …

We summarize the ongoing scientific program of the 12 GeV Continuous Electron Beam
Accelerator Facility (CEBAF) and give an outlook into future opportunities. The program …

Using a sample of (10.09±0.04)× 10 9 J/ψ events collected with the BESIII detector operating
at the BEPCII storage ring, a partial wave analysis of the decay J/ψ→ γ η η′ is performed …

The cross sections of e+ e-→ π+ π-hc at center-of-mass energies from 3.896 to 4.600 GeV
are measured using data samples collected with the BESIII detector operating at the Beijing …

The past decade witnessed a remarkable proliferation of exotic charmonium-like
resonances discovered at accelerators. In particular, the recently observed charged states …

A review of the theoretical and experimental status of hybrid hadrons is presented. The
states π 1 (1400), π 1 (1600), and π 1 (2015) are thoroughly reviewed, along with …

We present the first determination of the hadronic decays of the lightest exotic JPC= 1-+
resonance in lattice QCD. Working with SU (3) flavor symmetry, where the up, down and …

Mapping states with explicit gluonic degrees of freedom in the light sector is a challenge,
and has led to controversies in the past. In particular, the experiments have reported two …

A bstract We present a spectrum of highly excited charmonium mesons up to around 4.5
GeV calculated using dynamical lattice QCD. Employing novel computational techniques …
