It is demonstrated that, if the lightest positive parity charm mesons are assumed to owe their existence to non-perturbative Goldstone boson-D/D∗ scattering, various puzzles in the charm meson spectrum get resolved. Most importantly the ordering of the lightest strange and non-strange scalars becomes natural. Furthermore, it is demonstrated that the amplitudes for Goldstone boson-D/D∗ scattering are fully consistent with the high quality data on decay B−→ D+π−π− provided by LHCb. It implies that the lowest positive-parity charm mesons are dynamically generated rather than quark-antiquark states.

The chiral structure of heavy-light mesons is explored with a particular focus on the nature of the DsJ charmed mesons. Theoretical predictions for the hadronic and radiative decays of these mesons are compared to recent experimental data.

The Regge spectrum of soft-wall holographic model is generalized to the case of arbitrary twist. Combining this result with the light-front holographic QCD, one arrives at a broad hydrogen-like degeneracy of the same sort as the degeneracy observed experimentally in the spectrum of light mesons.
