✦ Synopsis

We present an on-shell ∆I = 3/2 K → ππ matrix element calculation. We achieve a ππ excited state with non-zero relative momentum by imposing anti-periodic boundary conditions on the π. By calculating the matrix element with a varying strange quark mass, we can interpolate to the on-shell matrix element.
