Scalar Meson σ Phase Motion at D+ → π−π+π+ Decay
We make a direct and model-independent measurement of the low π+π− mass phase motion in the D+ →π−π+π+ decay. Our preliminary results show a strong phase variation, compatible with the isoscalar σ(500)meson. This result confirms our previous result [1]...
