Pion mass dependence in Dπ scattering and the D0*(2300) resonance from lattice QCD
Lattice QCD results for isospin I=12 Dπ scattering are presented. Utilizing a series of Nf=2+1 Wilson-Clover ensembles with pion masses of mπ≈133, 208, 305, and 317 MeV, various two-particle operators are constructed, and the corresponding finite-volume spectra are determined. The S- and P-wave scattering phase shifts are extracted using the Lüscher approach. A clear trend for the motion of the D0*(2300) pole is identified. With the physical pion mass configurations also included, this calculation constitutes the first lattice calculation in which the pion mass dependence of the D0*(2300) pole is investigated and the scattering lengths are extrapolated/interpolated to the physical pion mass in Dπ scattering.
