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” …

Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

Abstract This White Paper aims at highlighting the important benefits in the science reach of
the EIC. High luminosity operation is generally desirable, as it enables producing and …

Chiral perturbation theory and its unitarized versions have played an important role in our
understanding of the low-energy strong interaction. Yet, so far, such studies typically deal …

According to the classification of the quark model, the hadrons going beyond three-quark
baryon and quark-antiquark meson pictures are called exotic hadrons. Many new hadrons …

This review treats the advances in Light Baryon Spectroscopy of the last two decades, which
were mainly obtained by measuring meson-production reactions at photon facilities all over …

We study the internal structure of a range of four-quark states with charm quark contributions
using a two-body Bethe–Salpeter equation. Thereby, we examine charmonium-like states …

We calculate the mass spectra of Λ c, Ξ c, Σ c, Ξ c′, and Ω c baryons in the framework of a
quark-diquark configuration using the relativistic flux tube model. The spin-dependent …

The Bell nonlocality and entanglement are two kinds of quantum correlations in quantum
systems. Due to the recent upgrade in the Beijing Spectrometer III (BESIII) experiment, it is …

In the present article, we employ the Regge phenomenology to describe the mass-spectra of
singly charmed baryons. With the assumption of linear Regge trajectories, the relations …
