Abstract

We discuss (π0,η,η′)→γ∗γ(\pi^0,\eta,\eta')\to\gamma^*\gamma transition form factors using the light-front quark model. Our discussion includes the analysis of the mixing angles for η−η′\eta-\eta'. Our results for Q2F(π0,η,η′)→γ∗γ(Q2)Q^2 F_{(\pi^0,\eta,\eta')\to\gamma^*\gamma}(Q^2) show scaling behavior for high Q2Q^2 consistent with pQCD predictions.
