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 …

Delta I Equals Three Halfs Kaon To Two Pion Decays Using Lattice Quantum Chromodynamics with Domain Wall Fermions
We calculate matrix elements for kaon to two pion decays in the 𝛥𝛪 = 3/2 channel using lattice gauge theory simulations. From these we can extract the decay amplitude 𝐴₂, for which the real part is related to the decay rate and can be compared to the experimental result Re(𝐴₂) = 1.484 x 10⁻⁸ GeV, …
