| dc.description | In this note, we clarify a point concerning the power divergence in lattice calculations of $ΔI = 1/2$ $K\toππ$ decay amplitudes. There have been worries that this divergence might show up in the Minkowski amplitudes at $M_{K}=M_π$ with all the mesons at rest. Here we demonstrate, via an explicit calculation in leading-order Chiral Perturbation Theory, that the power divergence is absent at the above kinematic point, as predicted by CPS symmetry. | |
