“…[1131], the authors found that the isoscalar Λ c Λc , Σ ( * ) c Σ( * ) c and isovector Λ c Σ( * ) c as well as their doubly charmed and doubly bottom counterparts are good candidates of the molecular hexaquarks. The calculations in various models [1132,581,1133,1134,1135,268,342,276,1136,1137,1138] In Ref. [393], the authors proposed an alternative way to determine the spins of the P c (4440) and P c (4457) from the spectrum of the Ξ ( * ) cc Σ ( * ) c systems with the help of lattice QCD [1140].…”

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.

“…Especially, we suggest several operational weak decay channels of B mesons or b-baryons to carry out the search for the predicted charmed-strange pentaquark system, which is a crucial step of constructing the "particle zoo 2.0". Mass spectrum of csnnn.-The mass spectrum of the csnnn pentaquark system is studied by considering the chromoelectric interactions (CEI) and the chromomagnetic interactions (CMI), which have been widely studied in various hadron systems [23][24][25][26][27][28][29]. The effective Hamiltonian for the masses of S-wave hadrons can be described by…”
