Sampling the Schwinger Model with Gauge-Equivariant Diffusion

Octavio Vega, Aida X. El-Khadra

We present a first study of a diffusion-based approach to accelerated sampling of the $N_{f} = 2$ lattice Schwinger model. Our work is inspired by recent and growing successes in dev…

Hadronic contributions to $I^\pm (Q^{2})$ and $sin^{2} I^¸_{W} (Q^{2})$ from spectral reconstruction of lattice-QCD data

AdriÃ¡n 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, $I^ I^\pm (Q^{2})$ , and the electroweak mixing angle,…

Untangling the heavy-flavor mess: status of the Fermilab-MILC calculation of the $B_{(s)} \to D_{(s)}^{(*)} ℓ I^½$ 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 I ¨ $ , $B_{(s)} \to D_{(s)}$ 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…

Towards determination of the strong coupling $I^\pm_{s} (m_{Z})$ from four-flavor lattice QCD using the continuous $I^^{2}$ -function method

Yash Mandlecha, Alexei Bazavov, Akhil Chauhan +10

The precise value of the strong coupling $I^\pm_{s} (m_{Z})$ at the $Z$ -boson mass $m_{Z}$ is essential for high-energy phenomenology and precision tests of quantum chromodynamics (QCD).…

Kaon leptonic and semileptonic decays with $N_{f} = 2 + 1 + 1$ HISQ fermions

RamÃ³n 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…
