Title: Scalar Meson {sigma}(500) Phase Motion at D+ {yields} {pi}-{pi}+{pi}+ Decay

Abstract

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