$D \to (K \pi)_{\mathbf{27}}$ at the SU(3)-flavour-symmetric point I: Methodology and strong phase determination
We present part one of an SU(3)-flavour-symmetric lattice QCD calculation of the amplitude for a $D$-meson decaying to a $K\pi$ final state in the 27-dimensional irreducible representation of the flavour symmetry group, denoted $(K\pi)_{\mathbf{27}}$. The Wilson--clover gauge ensembles used in this work, generated by t...
