Update of Euclidean windows of the hadronic vacuum polarization
/ RBC Collaboration
We compute the standard Euclidean window of the hadronic vacuum polarization using multiple independent blinded analyses. We improve the continuum and infinite-volume extrapolations of the dominant quark-connected light-quark isospin-symmetric contribution and address additional sub-leading systematic effects from sea-charm quarks and residual chiral-symmetry breaking from first principles.

First results from the Muon g-2 Experiment at Fermilab
/ Lehner, Christoph (speaker) (University of Regensburg & BNL) ; Venanzoni, Graziano (speaker) (INFN)
The ultimate precision in the measurement of the muon anomaly, $a_\mu$ = (g – 2)/2, has been constantly pursued since the sixties, when CERN played a leading role in its determination with a series of pioneering experiments that ran until the late seventies. The present most accurate $a_\mu$ measurement was carried out by the E821 Experiment at Brookhaven (USA), resulting in a 3.7 standard deviation discrepancy with the theoretical prediction of the Standard Model of particle physics [...]

Lattice determination of $I= 0$ and 2 $\pi\pi$ scattering phase shifts with a physical pion mass
/ RBC Collaboration
Phase shifts for $s$-wave $\pi\pi$ scattering in both the $I=0$ and $I=2$ channels are determined from a lattice QCD calculation performed on 741 gauge configurations obeying G-parity boundary conditions with a physical pion mass and lattice size of $32^3\times 64$. These results support our recent study of direct CP violation in $K\to\pi\pi$ decay \cite{Abbott:2020hxn}, improving our earlier 2015 calculation \cite{Bai:2015nea}. [...]

Hadronic light-by-light contribution to the muon anomalous magnetic moment from lattice QCD
/ Blum, Thomas (Connecticut U. ; RIKEN BNL) ; Jin, Luchang (Connecticut U. ; RIKEN BNL) ; Christ, Norman (Columbia U.) ; Hayakawa, Masashi (Nagoya U. ; Nishina Ctr., RIKEN) ; Izubuchi, Taku (Brookhaven ; RIKEN BNL) ; Jin, Luchang (Connecticut U. ; RIKEN BNL) ; Jung, Chulwoo (Brookhaven) ; Lehner, Christoph (Brookhaven ; Regensburg U.)
We report preliminary results for the hadronic light-by-light scattering contribution to the muon anomalous magnetic moment. Several ensembles using 2+1 flavors of M\"obius domain-wall fermions, generated by the RBC/UKQCD collaborations, are employed to take the continuum and infinite volume limits of finite volume lattice QED+QCD [...]

We review the present status of the Standard Model calculation of the anomalous magnetic moment of the muon. This is performed in a perturbative expansion in the fine-structure constant $\alpha$ and is broken down into pure QED, electroweak, and hadronic contributions. [...]

Exclusive Channel Study of the Muon HVP
/ Bruno, Mattia (CERN) ; Izubuchi, Taku (Brookhaven ; RIKEN BNL) ; Lehner, Christoph (U. Regensburg (main) ; Brookhaven) ; Meyer, Aaron S. (Brookhaven)
The Hadronic Vacuum Polarization (HVP) is a dominant contribution to the theoretical uncertainty of the muon anomalous magnetic moment. The uncertainty in a lattice QCD calculation of the connected light-quark contribution to the HVP is dominated by the long-distance region of the vector correlation function. [...]
