“…In the framework of the modified chromomagnetic interaction (CMI) model, the mass spectra for the ground fully heavy pentaquarks QQQQ Q has been systematically investigated [68], and a J P = 3/2 − ccbb b state is considered as a good stable candidate which cannot decay through the strong interaction. In the framework of the chiral quark model and quark delocalization color screening model, Yan et.al systematically investigate the ccccc and bbbb b states and obtain three bound three fully heavy pentaquarks [74]. However, it still need to be further confirmed by solving accurately the fivebody problem for the configurations as pointed in Ref.…”

“…[41][42][43][44][45], the compact tetraquark and hadronic molecule pictures are taken into account simultaneously. According to the LHCb measurements, the rather closeness of the T + cc mass to the D * + D 0 threshold strongly favors the molecular explanation concerning the T + cc nature [46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61]. This is similar to the case of the famous X (3872) state, which is widely supposed to be a weakly bound hadronic molecule composed of D * D/D D * .…”

In this work, we propose to search for the exotic doubly charmed meson $$T_{cc}^+$$ T cc + and its analog $$T_{cc\bar{s}}^+$$ T c c s ¯ + in $$B_c^+$$ B c + decays, which provide a good environment for the formation of the exotic state containing double charm quarks. Within the molecular scheme, the production of $$T_{cc}^+$$ T cc + and $$T_{cc\bar{s}}^+$$ T c c s ¯ + through various rescattering processes with different intermediate states are investigated. For the moderate values of model parameters, the branching ratios of $$B_c^+$$ B c + decaying into $$T_{cc}^+ \bar{D}^{0}$$ T cc + D ¯ 0 , $$T_{cc}^+ \bar{D}^{*0}$$ T cc + D ¯ ∗ 0 , $$T_{cc\bar{s}}^+ \bar{D}^{0}$$ T c c s ¯ + D ¯ 0 and $$T_{cc\bar{s}}^+ \bar{D}^{*0}$$ T c c s ¯ + D ¯ ∗ 0 are estimated to be of the order of $$10^{-7}$$ 10 - 7 , $$10^{-5}$$ 10 - 5 , $$10^{-6}$$ 10 - 6 and $$10^{-4}$$ 10 - 4 , respectively, which may be tested by future experiments.

“…The discovery of the P c states and the evidence of the P cs also inspired the investigation of the other pentaquark states, such as QQqq q [418,419,420,421,422,423,420,424], P css [425], the fully heavy pentaquark state [426,427], the Qqqqq [428,429,430,431,432], BΞ c and BΞ c bound states [433], etc.…”

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.
