The past decades witnessed the golden era of hadron physics. Many excited open heavy flavor mesons and baryons have been observed since 2017. We shall provide an updated review of the recent experimental and theoretical progresses in this active field. Besides the conventional heavy hadrons, we shall also review the recently observed open heavy flavor tetraquark states X(2900) and T + cc (3875) as well as the hidden heavy flavor multiquark states X(6900), P cs (4459) 0 , Z cs (3985) − , Z cs (4000) + , and Z cs (4220) + . We will also cover the recent progresses on the glueballs and light hybrid mesons, which are the direct manifestations of the non-Abelian SU (3) gauge interaction of the Quantum Chromodynamics in the low-energy region.

“…With the accumulation of experimental data, more and more new hadrons have been discovered in the past decades [80,81]. Especially, with the running of LHCb, the studies of heavy flavor hadron enter a new era [82]. When facing on this issue, we have reasons to believe that more progresses on the heavy flavor hadron will be made in the near future.…”

The dynamical similarity which exists between the λ-mode excited bbq baryons (q refers to the u, d, and s quarks) and the bq mesons inspired us to carry out a combined study of their spectroscopy. In this work, the masses and strong decays of these low-lying b q and bbq states are studied by the same theoretical methods, and the dynamical similarity which is implied in their mass spectra and strong decays are also discussed. The recent discovered bq states, including the B J (5840), B J (5970), B sJ (6064), and B sJ (6114), are analyzed. According to our result, the B J (5840) could be assigned as a 2S state, while the B J (5970) could be regarded as a member of the 1D(2 − , 3 − ) jq=5/2 doublet. The B sJ (6064) and B sJ (6114) are probably the D-wave states. Especially, they could be explained as the members of the 1D(1 − , 2 − ) jq=3/2 and 1D(2 − , 3 − ) jq=5/2 doublets, respectively. The predicted masses and decay properties of other unknown bq/bbq states may provide useful clues to the future experiment.

“…In the past decades, the hadron spectroscopy has been revived by the observation of many excited heavy hadrons [1], the exotic X, Y, Z states [1], and the hidden-charm pentaquark states [2,3] as well as the doubly charmed teraquark state T cc [4,5], etc. Readers may find more experimental and theoretical details in the reviews [6,7,8,9,10,11,12,13,14,15,16,17]. The traditional quark model failed badly for most of these states.…”

Chiral symmetry and its spontaneous breaking play an important role both in the light hadron and heavy hadron systems. In this work, we shall review the investigations on the chiral corrections to the properties of the heavy mesons and baryons within the framework of the chiral perturbation theory (χPT). We will also review the scatterings of the light pseudoscalar mesons and heavy hadrons. Moreover, the modern nuclear force was built upon the chiral effective field theory (χEFT). In the past decades many new hadron states were observed experimentally. A large group of these states are near-threshold resonances, such as the charged charmoniumlike Z c and Z cs states, bottomoniumlike Z b states, hidden-charm pentaquark P c and P cs states and the doubly charmed T cc state etc. They are very good candidates of the loosely bound molecular states composed of a pair of charmed hadrons. The same chiral dynamics not only governs the nuclei and forms the deuteron, but also dictates the above shallow bound states or resonances. We will perform an extensive review on the progress on the heavy hadronic molecular states within the framework of χEFT.
