$K^{+}\to\pi^{+}\pi^{0}$ decays at next-to-leading order in the chiral expansion on finite volumes
We present the ingredients for determining $K^{+}\to\pi^{+}\pi^{0}$ matrix elements via the combination of lattice QCD and chiral perturbation theory ($\chi$PT). By simulating these matrix elements at unphysical kinematics, it is possible to determine all the low-energy constants (LECs) for construc...
