The $γ π \to π π$ anomaly from lattice QCD and dispersion relations

Malwin Niehus, Martin Hoferichter, Bastian Kubis

We propose a formalism to extract the $γ π \to π π$ chiral anomaly $F_{3 π}$ from calculations in lattice QCD performed at larger-than-physical pion masses. To this end, we start from a…

Chiral extrapolation of hadronic vacuum polarization

Gilberto Colangelo, Martin Hoferichter, Bastian Kubis +2

We study the pion-mass dependence of the two-pion channel in the hadronic-vacuum-polarization (HVP) contribution to the anomalous magnetic moment of the muon $a_{μ}^{HVP}$ , by u…
