Chiral extrapolation of hadronic vacuum polarization and isospin-breaking corrections
Martin Hoferichter, Gilberto Colangelo, Bai-Long Hoid +4
By far the biggest contribution to hadronic vacuum polarization (HVP) arises from the two-pion channel. Its quark-mass dependence can be evaluated by combining dispersion relations…
Isospin-breaking effects in the two-pion contribution to hadronic vacuum polarization
Gilberto Colangelo, Martin Hoferichter, Bastian Kubis +1
Isospin-breaking (IB) effects in the two-pion contribution to hadronic vacuum polarization (HVP) can be resonantly enhanced, if related to the interference of the and $ω(7…
Data-driven evaluations of Euclidean windows to scrutinize hadronic vacuum polarization
G. Colangelo, A. X. El-Khadra, M. Hoferichter +4
In this paper, we discuss how windows in Euclidean time can be used to isolate the origin of potential conflicts between evaluations of the hadronic-vacuum-polarization (HVP) contr…
Prospects for precise predictions of in the Standard Model
G. Colangelo, M. Davier, A. X. El-Khadra +79
We discuss the prospects for improving the precision on the hadronic corrections to the anomalous magnetic moment of the muon, and the plans of the Muon Theory Initiative to…
Kaon electromagnetic form factors in dispersion theory
Dominik Stamen, Deepti Hariharan, Martin Hoferichter +2
The electromagnetic form factors of charged and neutral kaons are strongly constrained by their low-energy singularities, in the isovector part from two-pion intermediate states an…
