Abstract: | After summarizing the properties of the socalled Dalitz Array (DA), which is a genuine characteristics of a resonance, we determine those of the well known ε, γ, andA 2 resonances produced in theK ? p→π+π?π0 Λ final state at 4.2 Ge V/c. A tentative measurement of the DA of theA 1 meson produced backwards in the reactionK ? p→π+π+π?Σ? is also presented. The data for this analysis come from the high statistics (130 events/μb) experiment performed by the ACNO Collaboration. |
