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,…
Untangling the heavy-flavor mess: status of the Fermilab-MILC calculation of the form factors
Alejandro Vaquero, Carleton DeTar, Aida El-Khadra +6
We present the status of calculations of the form factors of the most relevant heavy-to-heavy and heavy-to-light decay channels. Using seven HISQ ensembles, with latt…
, from 2+1+1 Flavor Lattice QCD
Nicholas Cassar, Akhil Chauhan, Carleton DeTar +8
We present a lattice-QCD calculation of the hadronic form factors for -meson semileptonic decays computed using the highly improved staggered quark action for both valence and s…
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 (…
