Abstract
In a previous re-analysis of the I=0 S-wave ππ-scattering phase shift, we have found evidence of a б particle accompanied by a negative “repulsive core”-type background phase shift. We make further analysis under the K threshold to determine the permissible range of б mass and width in accordance with present experimental data.Keywords
