The Causal Bootstrap: Bounding Smeared Spectral Functions from Non-Perturbative Euclidean Data
Ryan Abbott, Sarah Fields, William I. Jay +2
This work introduces the causal bootstrap, a framework for bounding smeared spectral observables from finite non-perturbative Euclidean data. The method optimizes over the convex s…
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…
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 (…
