Description

In my talk, I will present our recent dispersive analysis of the $\gamma \gamma^\star \to \pi\pi, \pi\eta$ processes from the threshold up to 1.4 GeV in the two photon invariant mass. These amplitudes serve as important input to constrain the hadronic piece of light-by-light scattering contribution to (g-2) and support the current experimental program at BESIII. As well, I will present an application of the light-by-light scattering sum rules to the $\gamma \gamma^\star$-production of mesons in light of the new data by the Belle Collaboration on the transition form factors.
