Hadronic light-by-light scattering in the muon g-2: impact of proposed
measurements of the (pi^0 -> gamma gamma) decay width and the (gamma^* gamma
-> pi^0) transition form factor with the KLOE-2 experiment [PDF]
Andreas NyffelerWe discuss, how planned measurements at KLOE-2 of the (pi^0 -> gamma gamma) decay width and the (gamma^* gamma -> pi^0) transition form factor can improve estimates for the numerically dominant pion-exchange contribution to hadronic light-by-light scattering in the muon g-2 and what are the limitations related to the modelling of the off-shellness of the pion.View original: http://arxiv.org/abs/1212.0738
