13. The Muon g-2 HVP contribution from the BMW/DMZ collaboration

Bálint Tóth (University of Wuppertal)

8/5/26, 10:30 AM

We present a complete calculation of the hadronic vacuum polarization contribution to the muon magnetic anomaly reaching the sub-5‰ precision level. Our result, recently published in Nature, constitues an unprecedented validation of the Standard Model, at the given accuracy, in explaining the experimental measurement world average of $a_\mu$, agreeing with the latter at 0.5 standard...

6. Update on $a_\mu^\text{HVP, isoQCD}$ from the ETM collaboration

Simone Romiti (University of Bern)

8/5/26, 11:00 AM

In this talk we review the status of the lattice calculation of the Hadronic Vacuum Polarization (HVP) contribution to $a_\mu=(g-2)_\mu$ from the ETM collaboration.
Our result includes the effects of the $u,d,s,c$ quarks in the isospin-symmetric limit of QCD. Our ensembles are generated with $N_f=2+1+1$ dynamical flavors through Wilson-clover twisted mass fermions, and our correlators are...

55. Lattice HVP from FNAL/HPQCD/MILC

Shaun Lahert (University of Utah)

8/5/26, 11:30 AM

22. Mainz status update

Arnau Beltran (JGU Mainz)

8/5/26, 12:00 PM

We present the Mainz update on the determination of the hadronic vacuum polarization contribution to the muon $g-2$. We discuss ongoing improvements to our dataset and ensemble set aimed at better constraining the chiral–continuum extrapolation, as well as our efforts toward a complete estimate of isospin-breaking effects. In addition, we report on our progress in the determination of...

35. PACS Collaboration for Muon g-2 Precision Physics

Kohtaroh Miura (University of Tsukuba)

8/5/26, 4:00 PM

I will report on the launch of the lattice QCD project by the PACS Collaboration (PACSc) for muon g-2 precision physics in collaboration with the J-PARC experiments. Using the Fugaku supercomputer, the PACSc has generated PACS10 gauge ensembles by adopting the stout-smeared O(a) improved Wilson-clover quark action and the Iwasaki gauge action at the physical pion/kaon masses on the lattice...
