Abstract
We update the numerical results for the s-wave pi pi scattering phase-shift difference delta_0^0 - delta_0^2 at s = m_K^2 from a previous study of isospin breaking in K to 2 pi amplitudes in chiral perturbation theory. We include recent data for the K_S to pi pi and K^+ to pi^+ pi^0 decay widths and include experimental correlations.
