Description
This work achieves the first analytical determination of the three-loop hadronic vacuum polarization contribution to the muon's anomalous magnetic moment ($g−2$). Leveraging cutting-edge amplitude techniques within chiral perturbation theory, the effective field theory for low-energy QCD, we present this infinite volume calculation. Our result is crucial for accurately estimating finite volume errors at this order and represents a significant advancement in high-precision $g−2$ calculations.
Work done in collaboration with Laurent Lellouch, Alessandro Lupo, Mattias Sjö et al.
