21. The lattice scale setting procedure in the BMW/DMZ muon (g-2) calculation

Davide Giusti (Forschungszentrum Jülich)

8/5/26, 4:15 PM

The lattice scale setting already represents, and will increasingly become in the future, one of the leading sources of uncertainty in first-principles calculations of the HVP contribution to $(g_\mu-2)$.
In this talk, I will discuss the procedure adopted in the BMW/DMZ collaboration calculation, which currently provides the most precise Standard Model determination of the muon anomalous...

10. Improved calculational setup for isospin-breaking corrections to the HVP contribution

Sebastian Lahrtz

8/5/26, 4:30 PM

Isospin-breaking corrections to the hadronic vacuum polarisation
contribution to the muon g-2 dominate the error of recent lattice
calculations. It is therefore crucial to reduce the uncertainties
coming from these contributions to reach the overall target
precision. I will present preliminary results from a new calculational
setup that improves the statistical precision for constant...

60. Spurion Matching of HVP and HLbL Diagrams

Jake Sitison (University of Colorado Boulder)

8/5/26, 5:00 PM

Chiral perturbation theory ($\chi$PT) is the effective field theory (EFT) of QCD at low energies and is routinely used to complement lattice QCD analyses. EFT matching can be used to relate objects, such as operators and correlators, in the UV theory (QCD) to those in the IR EFT ($\chi$PT). In this talk, we present a charge matrix spurion analysis to match diagrams with external vector...
