Abstract

We show that the lattice calculation of (Formula presented) and (Formula presented) amplitudes for (8,1) and (27,1) operators to (Formula presented) in chiral perturbation theory is feasible when one uses (Formula presented) computations at the two unphysical kinematics allowed by the Maiani-Testa theorem, along with the usual (computable) two- and three-point functions, namely (Formula presented) (Formula presented) (with momentum), and (Formula presented) Explicit expressions for the finite logarithms emerging from our (Formula presented) analysis to the above amplitudes are also given.
