Kaon to two pions decays from lattice QCD: ΔI=1/2 rule and CP violation
… a direct lattice calculation of the K to ππ decay matrix elements for both the ΔI = 1/2 and 3/2 amplitudes A0 and A2 on a 2+1 flavor, domain wall fermion, 163 × 32 × 16 lattice ensemble and a 243 × 64 × 16 lattice ensemble. This is a complete calculation in which all contractions for the …

Precision Lattice Calculation of Kaon Decays with Möbius Domain Wall Fermions
… lattice calculation of the semileptonic kaon decay K→πlν using these newly generated high quality lattice ensembles. Our main result is the form factor f^±{Kπ}(q²) evaluated directly at zero momentum transfer q²=0. Free of various systematic errors, this new result can be used to determine the …
