Rescattering effects in the hadronic-light-by-light contribution to the anomalous magnetic moment of the muon
We present a first model-independent calculation of ππ intermediate states in the hadronic-light-by-light (HLBL) contribution to the anomalous magnetic moment of the muon (g-2)μ that goes beyond the scalar QED pion loop. To this end, we combine a recently developed dispersive description of the HLBL...
