Abstract

We review our evaluation of forward dispersion relations for direct fits to the different, and often conflicting, ππ scattering experimental analyses. We find that some of the most commonly used data sets do not satisfy these constraints by several standard deviations. We also provide a consistent ππ amplitude by improving a global fit to data with these dispersion relations.
