We calculate the S-wave scattering lengths for charmed mesons scattering off Goldstone bosons and explore their quark mass dependence using chiral perturbation theory up to next-to-leading order as well as a unitarized version of it. The quark mass dependence of all scattering lengths determined in a recent lattice calculation can be reproduced by the unitarized version. We also discuss signals of possible bound states in these observables.

  1. Exotic $T^*_{csJ}$ and $T^*_{c\bar{s}J}$ states and coupled-channel scattering at the $SU(3)$ flavour symmetric point from lattice QCD

    hep-lat 2026-04 unverdicted novelty 8.0

    First lattice QCD calculation at the SU(3) flavour symmetric point finds poles in exotic charm-light meson scattering amplitudes, linking a J^P=0+ resonance to experimental T*cs0(2870)^0 and T*c s-bar0(2900) states an...

  2. Revealing the $D_0^*(2300)$ two-pole structure from lattice data and the SU(3) limit

    hep-ph 2026-06 unverdicted novelty 7.0

    Lattice data analysis with UChPT finds two I=1/2 poles at physical point with positions 2094-i111 MeV and 2463-i108 MeV; lower pole splits like the sigma on ms=const trajectory and links to 3-bar, higher pole links to...

  3. Analysis of the $D_0^*(2300)$ resonance from lattice QCD under chiral symmetry

    hep-ph 2026-04 unverdicted novelty 7.0

    Chiral symmetry corrections in lattice QCD fits shift the D0*(2300) resonance pole closer to the Dπ threshold and reduce its width, while coupled channels produce a two-pole structure.

  4. $D_1$ and $D_2$ resonances in coupled-channel scattering amplitudes from lattice QCD

    hep-lat 2025-02 unverdicted novelty 7.0

    Lattice QCD at m_π≈391 MeV finds D1 bound state below D*π threshold strongly coupled in S-wave and D1' resonance in elastic D*π region for I=1/2 charmed channels.

  5. The $D_{s1}(2460)$ and other open-charm $1^+$ states in relativistic chiral effective field theory

    hep-ph 2026-07 unverdicted novelty 6.0

    Relativistic U(3) chiral EFT at NLO yields scattering lengths that match lattice data and identifies D_s1(2460) as an SU(3) triplet bound-state pole and D1(2430) as a triplet-sextet pole pair, none of which are conven...
