Scalar meson σ(500) phase motion at D+ → π-π+π+ decay

Description

Applying the Amplitude Difference Method to Fermilab experiment E791 D+ → π-π+π+ data, we measure the low mass π+π- phase motion. Our results suggest a significant phase variation, compatible with the existence of an isoscalar σ(500) meson, as previously reported using an isobar model fit to the full Dalitz-plot density.
