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 conventional q-bar q states.
Theoretical predictions show that femtoscopic correlation functions for neutral Σ_c^0 π^- pairs best constrain isotensor strong interactions in charm and bottom sectors, while Coulomb repulsion diminishes discriminating power in charged channels.
