Abstract:Patterns of chiral symmetry violation and tests of the conservation of the fundamental C, P and CP symmetries are key physics issues in studies of the π 0 , η and η ½ meson decays. These tests include searches for rare or forbidden decays and searches for asymmetries among the decay products in the not-so-rare decays. Some examples for the rare decays are η 2π, η 4π 0 (CP tests), decays into an odd number of photons (e.g., η 3γ) and the decay η π 0 e e ¡ (C tests). In the conversion decay η π π ¡ e e ¡ , the a… Show more
