Hadronic contributions to and from spectral reconstruction of lattice-QCD data
Adrián del Pino, David A. Clarke, Carleton DeTar +17
We present preliminary results from a lattice-QCD study of the hadronic contributions to the running of the electromagnetic coupling, , and the electroweak mixing angle,…
Towards determination of the strong coupling from four-flavor lattice QCD using the continuous -function method
Yash Mandlecha, Alexei Bazavov, Akhil Chauhan +10
The precise value of the strong coupling at the -boson mass is essential for high-energy phenomenology and precision tests of quantum chromodynamics (QCD).…
Kaon leptonic and semileptonic decays with HISQ fermions
Ramón Merino, Alexei Bazavov, Claude W. Bernard +9
Precision tests of the Standard Model (SM) currently show a deficit in first-row Cabibbo-Kobayashi-Maskawa (CKM) unitarity. In this talk, we discuss progress towards a correlated a…
High-Precision Scale Setting with the Omega-Baryon Mass and Gradient Flow
Alexei Bazavov, Claude W. Bernard, David A. Clarke +23
The gradient-flow scale in lattice QCD is determined using the mass of the baryon to set the physical scale. Nine ensembles using the highly improved staggered quark (…
The anomalous magnetic moment of the muon in the Standard Model: an update
R. Aliberti, T. Aoyama, E. Balzani +232
We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, , updating the first White Paper (WP20) [1]. The pure QED and electroweak contri…
Hadronic vacuum polarization for the muon from lattice QCD: Long-distance and full light-quark connected contribution
Alexei Bazavov, Claude W. Bernard, David A. Clarke +22
We present results for the dominant light-quark connected contribution to the long-distance window (LD) of the hadronic vacuum polarization contribution (HVP) to the muon fro…
