“…The interpretation of the T + cc as the DD * molecular state with (I)J P = (0)1 + was supported by [539] within the QCD sum rule method, but not supported by [540] through the same approach. Besides, the Bethe-Salpeter equation was applied in [541,542] to explain the T + cc as the DD * molecular state of (I)J P = (0)1 + . The binding energy of its beauty-partner was calculated in [542] to be 17.38 MeV.…”

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 Tcc(3875) as well as the hidden heavy flavor multiquark states X(6900), Pcs(4459), Zcs(3985), Zcs(4000), and Zcs(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.

“…[38][39][40][41], 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 [42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57]. 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 and its analog T + ccs in 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 and T + ccs through various rescattering processes with different intermediate states are investigated. For the moderate values of model parameters, the branching ratios of B + c decaying into T + cc D0 , T + cc D * 0 , T + ccs D0 and T + ccs D * 0 are estimated to be of the order of 10 −7 , 10 −5 , 10 −6 and 10 −4 , respectively, which may be tested by future experiments.

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.
