The Eta - Pi0 Ambiguity

Abstract

The a₀ and f₀ decays of the meson both result in 5 final states with the invariant mass of the . Because of the 15 different ways to combine the photons in two pairs, it is possible for events to have combinations that resemble both ⁰ and ^{0 0} . The events from each of the two reactions are generated by Monte Carlo, and tested for the two hypotheses in this study which is described in three short reports.
