Description

In my talk, I will present our recent dispersive analysis of the gamma* gamma* -> pipi/ pieta processes from the threshold up to 1.4 GeV in the two-photon invariant mass. These amplitudes serve as an important input to constrain the hadronic piece of light-by-light scattering contribution to (g-2) and support the current experimental program at BESIII.
