Description

Motivated by the need of experimental input to improve the Standard Model prediction of the anomalous magnetic moment of the muon $a_\mu$, the BESIII collaboration started a dedicated program to measure hadronic cross sections as well as transition form factors (TFF) with high accuracy. In this presentation we will focus on the two-photon physics program, which is dedicated to the measurement of TFFs. The data acquired at BESIII allow to study the momentum dependence of the TFFs of light pseudoscalar mesons dominating the hadronic Light-by-Light contribution to $a_\mu$ in the relevant kinematic region. The current status and ongoing investigations of will be discussed.
