A coupled channel analysis of the D * + D 0 and D * 0 D + system is performed to study the doubly charmed T + cc state recently discovered by the LHCb collaboration. We use a simple model for the scattering amplitude that allows us to describe well the experimental spectrum, and obtain the T + cc pole in the coupled channel T -matrix. We find that this bound state has a large molecular component. The isospin (I = 0 or I = 1) of the state cannot be inferred from the D 0 D 0 π + spectrum alone. Therefore, we use the same formalism to predict other DDπ spectra. In the case the T + cc has I = 1, we also predict the location of the other two members (T ++ cc and T 0 cc ) of the triplet. Finally, using Heavy-Quark Spin Symmetry, we predict the location of possible heavier D * D * (I = 0 or I = 1) partners.

“…The present experimental data cannot be applied to distinguish them. Under different assignment to the the T + cc , the investigations of the mass spectrum [35][36][37][38][39][40][41][42][43][44][45][46][47][48], decay behavior [49][50][51][52], and production mechanism [53][54][55][56] can provide some important aspect of the spectroscopy behavior of the T + cc . However, it is not the whole aspect of exploring hadronic spectroscopy.…”

In this work, we study the reaction of a nucleon and a doubly charmed state T cc . Under the assumption of the T cc as a molecular state of D * D, the reaction of the nucleon and T cc is mediated by exchanges of π, η, ρ, and ω meson, which results in split of T cc state with two D mesons in final state. With the help of the effective Lagrangians, the cross section of p + T + cc → p + D + + D 0 process is calculated, and a very large cross section can be obtained with very small incoming momentum of proton. It decrease rapidly with the increase of the momentum to about 10 mb at momenta of order of GeV. Such large cross section suggests that induced by a proton the T + cc state is very easy to decay and transit to two D mesons. In the rest frame of the T + cc state, an obvious accumulation of final D meson at small momentum region can be observed in predicted Dalitz plot, which is due to the molecular state interpretation of T cc state. This novel quasi-fission phenomenon of double charm molecular T + cc state induced by a proton can be accessible at the forthcoming PANDA experiment.

Motivated by the latest discovery of a new tetraquark T c c + with two charm quarks and two light antiquarks by LHCb Collaboration, we investigated the D D ∗ hadronic molecule interpretation of T c c + . By calculation, the mass and the decay width of this new structure T c c + can be understood in one-meson exchange potential model. The binding energies for these D D ∗ hadronic molecules with J P = 1 + are around 1 MeV. Besides, we also studied the possible beauty partners T b b 10598 of hadronic molecule T c c + , which may be feasible in future LHCb experiments.
