The muon g-2 in the light of two photon physics and first lessons from the LHC
Prof. Fred Jegerlehner (Humboldt-Universität, Berlin)

I give a brief summary of the status of the muon anomaly and then focus on problems in the determination of the hadronic light-by-light contribution. The latter is the challenge in reducing theoretical uncertainties to match the precision of new experiments expected to go into operation within a few years from now. The interplay with new, to be done, two photon physic experiments is emphasized. I will discuss how yet to be collected experimental data can constrain better the non-perturbative amplitudes required. The impact of recent LHC results for the interpretation of the muon g-2 "discrepancy" is briefly discussed.
