Correlation ofππ-Scattering Angle and Di-Pion Mass in the Vicinity of theρMeson

Abstract
One observed deviation from the expectations of the one-pion-exchange model in ρ-meson production has been presented as evidence for a new T=0, J=0 resonance. We show that a similar effect is seen in a state which cannot have T=0 and, therefore, must have another explanation.
