The past seventeen years have witnessed tremendous progress on the experimental and
theoretical explorations of the multiquark states. The hidden-charm and hidden-bottom …

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 …

In the past two decades, a plethora of hadronic states beyond the conventional quark model
of qq ̄ mesons and qqq baryons have been observed experimentally, which motivated …

Since the discovery of the first charmed meson in 1976, many open-charm and open-bottom
hadrons were observed. In 2003 two narrow charm-strange states $ D_ {s0}^{\ast}(2317) …

This article presents the first measurement of the interaction between charm hadrons and
nucleons. The two-particle momentum correlations of p D-and p¯ D+ pairs are measured by …

We review the recent status of the QCD sum rule approach to study the properties of
hadrons in vacuum and in hot or dense matter. Special focus is laid on the progress made in …

The DK interaction in isospin zero is known to be attractive to such an extent that a bound
state can be generated, which can be associated with the mysterious D s 0*(2317). In this …

In our quest to win a deeper understanding of how QCD actually works, the study of the
binding of heavy quarkonia and heavy-flavor hadrons to atomic nuclei offers enormous …

The formation of hadrons is a fundamental process in nature that can be investigated at
particle colliders. As several recent findings demonstrate, with\(\textrm {e}^{+}\textrm {e}^{-}\) …

In this paper, we investigate the hidden-charm pentaquarks as D¯(*) Λ c and D¯(*) Σ c (*)
molecules coupled to the five-quark states. Furthermore, we extend our calculations to the …
