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 (H…
Improving HISQ propagator solves using deflation
Leon Hostetler, M. A. Clark, Carleton DeTar +2
Typically, the conjugate gradient (CG) algorithm employs mixed precision and even-odd preconditioning to compute propagators for highly improved staggered quarks (HISQ). This appro…

Pietro Butti, Carleton DeTar, Aida El-Khadra +9
We present an update on the analysis of semileptonic decays at non-zero recoil. Our computation employs FNAL-MILC ensembles with highly improved…
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…
Hadronic vacuum polarization for the muon from lattice QCD: Complete short and intermediate windows

We present complete results for the hadronic vacuum polarization (HVP) contribution to the muon anomalous magnetic moment in the short- and intermediate-distance window regio…
The two-pion contribution to the hadronic vacuum polarization with staggered quarks
Shaun Lahert, Carleton DeTar, Aida X. El-Khadra +3
We present results from the first lattice QCD calculation of the two-pion contributions to the light-quark connected vector-current correlation function obtained from staggered-qua…

Andrew Lytle, Carleton DeTar, Aida El-Khadra +7
We present an update for results on -meson semileptonic decays using the highly improved staggered quark (HISQ) action for both valence and 2+1+1 sea quarks. The use of the high…
Form factors for semileptonic B-decays with HISQ light quarks and clover b-quarks in Fermilab interpretation
