“…Similarly, consistency with experiment has been shown in J/ψ → φ(ω)R [14], with R any of the resonances of [11], and in J/ψ radiative decays in [15]. The extension of these ideas to the charm and hidden charm sector have also shown that some of the excited D states and X,Y,Z states recently reported could be explained in terms of molecules involving mesons with charm [16][17][18][19][20][21][22].…”

We present a coupled channel unitary approach to obtain states dynamically generated from the meson baryon interaction with hidden charm, using constraints of heavy quark spin symmetry. We use as basis of states,DB,D * B states, with B baryon charmed states belonging to the 20 representations of SU(4) with J P = 1/2 + , 3/2 + . In addition we also include the η c N and J/ψN states. The inclusion of these coupled channels is demanded by heavy quark spin symmetry, since in the large m Q limit the D and D * states are degenerate and are obtained from each other by means of a spin rotation, under which QCD is invariant. The novelty in the work is that we use dynamics from the extrapolation of the local hidden gauge model to SU(4) and we show that this dynamics fully respects the constraints of heavy quark spin symmetry.With the full space of states demanded by the heavy quark spin symmetry and the dynamics of the local hidden gauge we look for states dynamically generated and find four basic states which are bound, corresponding toDΣ c ,DΣ * c ,D * Σ c andD * Σ * c , decaying mostly into η c N and J/ψN . All the states appear in isospin I = 1/2 and we find no bound states or resonances in I = 3/2. TheDΣ c state appears in J = 1/2, theDΣ * c in J = 3/2, theD * Σ c appears nearly degenerate in J = 1/2, 3/2 and theD * Σ * c appears nearly degenerate in J = 1/2, 3/2, 5/2, with the peculiarity that in J = 5/2 the state has zero width in the space of states chosen. All the states are bound with about 50 MeV with respect to the correspondingDB thresholds and the width, except for the J = 5/2 state, is also of the same order of magnitude.

In this talk we review the vector-vector and vector-baryon interaction within the hidden gauge formalism in a coupled channel unitary approach. The vector-vector interaction is studied for all the sectors not studied before: C = 0; S = 1 (hidden-charm), C = 1, S = 1, and the flavor exotic sectors C = 1; S = −1, 2 and C = 2; S = 0, 1, 2. We find nine states, four of them in the C = 1; S = 1 sector, where one can be identified with the D * s2 (2573) and it is interpreted as a D * K * molecular state. The other five resonances are found in the flavor exotic sectors C = 1; S = −1, C = 2; S = 0, 1 and can be considered as D * K * , D * D * and D * s D * molecular states. In the case of the vector-baryon interaction we generate hidden charm resonances around 4.3 GeV, without or with strangeness, N * , Λ * . Nevertheless, there is not experimental evidence of such states yet.

“…The molecular picture can also be applied to further states, though the vector-vector interaction does not always provide sufficient attraction. Only those carrying the quantum number hidden charm (C = 0; S = 0), (C = 1; S = −1, 0, 1) and (C = 2; S = 0, 1), form molecules of two D * mesons or D * and ρ, K * [22,23]. Some of these cases are flavour exotics since they can not be reached by qq [23].…”

Several observed states close to the DD * and D * (s)D * (s) thresholds, as the X(3872) and some XYZ particles can be described in terms of a two-meson molecule. Furthermore, doubly charmed states are also predicted. These new states are near the D * D * and D * D * s thresholds, and have spin-parity J P = 1 + . Their natural decay modes are D (s) D * , DD (s) π and DD (s) γ and D * D (s) γ. We evaluate the widths of these states, named here as R cc (3970) and S cc (4100), and obtain 44 MeV for the non-strangeness, and 24 MeV for the doubly charm-strange state. Essentially, the decay modes are DD (s) π and DD (s) γ, being the Dπ and Dγ emitted by one of the D * meson which forms the molecule.
