Abstract :
We report the results on the radiatve decays θ → η′γ, θ → π0π0γ and θ → ηπ0γ obtained with the KLOE detector at the DAΦNE θ-factory, using a sample of ∼ 16 pb−1. The value of the branching ratio for the θ → η′γ decay is related to the View the MathML source and gluon content of the η′. A fit to the two-pseudoscalar invariant mass for the π0π0γ and ηπ0γ final states gives the contribution of the direct terms θ → f0γ, σ → σγ and θ → a0γ, allowing us to investigate the nature of these light scalar mesons.
