Hadronic contributions to $α (Q^{2})$ and $sin^{2} θ_{W} (Q^{2})$ 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, $Δ α (Q^{2})$ , and the electroweak mixing angle, $…

Untangling the heavy-flavor mess: status of the Fermilab-MILC calculation of the $B_{(s)} \to D_{(s)}^{(*)} ℓ ν$ 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 $N_{f} = 2 + 1 + 1$ HISQ ensembles, with latt…

$B \to π$ , $B_{(s)} \to D_{(s)}$ 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 $B$ -meson semileptonic decays computed using the highly improved staggered quark action for both valence and s…

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 $w_{0}$ in lattice QCD is determined using the mass of the $Ω^{-}$ baryon to set the physical scale. Nine ensembles using the highly improved staggered quark (H…

$B \to D^{(*)}$ decays from $N_{f} = 2 + 1 + 1$ highly improved staggered quarks and clover $b$ -quark in the Fermilab interpretation

Pietro Butti, Carleton DeTar, Aida El-Khadra +9

We present an update on the analysis of semileptonic $B \to D^{(*)}$ decays at non-zero recoil. Our computation employs $2 + 1 + 1$ FNAL-MILC ensembles with highly improved…

Using AI for Efficient Statistical Inference of Lattice Correlators Across Mass Parameters

Octavio Vega, Andrew Lytle, Jiayu Shen +1

Lattice QCD is notorious for its computational expense. Modern lattice simulations require large-scale computational resources to handle the large number of Dirac operator inversio…
