The elliptic three-loop integrals of hadronic vacuum polarization in chiral perturbation theory
Laurent Lellouch, Alessandro Lupo, Mattias Sjö +1
This work presents a detailed account of the Feynman integrals required for the three-loop hadronic vacuum polarization calculation performed in arXiv:2510.12885. We explain how to…

The three-loop hadronic vacuum polarization in chiral perturbation theory
Mattias Sjö, Laurent Lellouch, Alessandro Lupo +2
Hadronic vacuum polarization is a key observable in low-energy QCD, and is famously the greatest contributor to the theoretical uncertainty in the muon magnetic moment. Its long-di…

Hadronic vacuum polarization to three loops in chiral perturbation theory
Laurent Lellouch, Alessandro Lupo, Mattias Sjö +2
Hadronic vacuum polarization at low virtualities limits the precision of experimental tests of the standard model via important physical observables. Here we compute that effect in…
