Correlations of C and CP violation in η → π 0 ℓ + ℓ − and η ′ → ηℓ + ℓ −

Correlations of C and CP violation in η → π 0 ℓ + ℓ − and η ′ → ηℓ + ℓ −

Abstract Based on recent progress in the systematic analysis of C and CP violation in the light-meson sector, we calculate the C-odd transition amplitudes η → π 0 ℓ + ℓ − and η ′ → ηℓ + ℓ − . Focusing on long-distance contributions driven by the lowest-lying hadronic intermediate states, we work out...
