Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

The last two decades have witnessed the discovery of a myriad of new and unexpected
hadrons. The future holds more surprises for us, thanks to new-generation experiments …

Map** 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 …

We have performed the most comprehensive resonance-model fit of π-π-π+ states using the
results of our previously published partial-wave analysis (PWA) of a large data set of …

Despite decades of research, we still lack a detailed quantitative understanding of the way
quantum chromodynamics (QCD) generates the spectrum of hadrons. Precise experimental …

Using lattice QCD we extract π π scattering amplitudes with isospin 0, 1, and 2 in low partial-
waves at two values of the light quark mass corresponding to m π∼ 283 and 330 MeV. We …

We perform a systematic analysis of the\(J/\psi\rightarrow\gamma\pi^ 0\pi^ 0\)
and\(\rightarrow\gamma K_S^ 0 K_S^ 0\) partial waves measured by BESIII. We use a large …

Resonant structures in the dipion mass spectrum from χ c 1 (3872)→ π+ π-J/ψ decays,
produced via B+→ K+ χ c 1 (3872) decays, are analyzed using proton-proton collision data …

We revisit the information on the two lightest a_0 a 0 resonances and S-wave π η π η
scattering that can be extracted from photon–photon scattering experiments. For this …

We apply a model-independent reconstruction method to experimental data in order to
identify complex poles of overlap** resonances. The algorithm is based on the …
