Description
The PANDA FAIR Phase-0 experiment at the Mainz Microtron (MAMI) accelerator facility at Mainz in Germany is set to determine the double-virtual transition form factor (TFF) of the neutral pion via single-pion electroproduction. The determination of the electroproduction cross section on a highly charged target using low momenta transfers gives access to the so-called virtual Primakoff contribution, which is proportional to the $\pi^{0}$ TFF. As a result, the experiment can contribute to reducing the uncertainty in the calculation of the hadronic light-by-light (HLbL) scattering contributions to the hadronic corrections of the anomalous magnetic moment of the muon (g$_\mu$-2 puzzle). The detector system for the experiment is a modified version of the PANDA backward calorimeter (EMC), developed by the electromagnetic process group (EMP) at HI-Mainz. The detector will operate in forward direction within a strong electromagnetic environment at the A1 electron scattering facility. The talk gives an update on both simulations and test measurements. Furthermore, the current status of the experiment preparation will be presented.
