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 lattice Schwinger model. Our work is inspired by recent and growing successes in dev…
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…
Towards a formalism for scattering from staggered lattice QCD
A. Dean. M. Valois, M. Dai, A. El-Khadra +3
Scattering processes featuring the strong interactions can be studied using lattice QCD by means of the Lüscher formalism. This approach relies on analyticity and unitarity of the…
, 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).…
