Beschreibung

In this talk, I discuss progress developing and applying the relativistic field-theoretic three-particle finite-volume scattering formalism to systems of nondegenerate mesons. In particular, I focus on the recently developed formalism for DDπ systems in the charm C = 2 sector. This includes the isospin-0 channel, in which the recently discovered doubly-charmed tetraquark Tcc(3875)+ is expected to manifest as a pole in the DDπDDπ scattering amplitude. The formalism presented here can also be applied to lattice QCD settings in which the D is bound and, in particular, remains valid below the left-hand cut in DD scattering, thus resolving an issue in previous analyses of lattice-determined finite-volume energies.
