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 (H…
decays from highly improved staggered quarks and clover -quark in the Fermilab interpretation
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…
Toward inclusive observables with staggered quarks: the smeared ~ratio
Thomas Blum, William I. Jay, Luchang Jin +2
Inclusive hadronic observables are ubiquitous in particle and nuclear physics. Computation of these observables using lattice QCD is challenging due the presence of a difficult inv…
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
Alexei Bazavov, David A. Clarke, Christine Davies +21
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…
-meson semileptonic decays from highly improved staggered quarks
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
Hwancheol Jeong, Carleton DeTar, Aida El-Khadra +7
We compute the vector, scalar, and tensor form factors for the , , and amplitudes, which are needed to describe semileptonic -meson decay rates for bo…
Long-Distance Nuclear Matrix Elements for Neutrinoless Double-Beta Decay from Lattice QCD
Zohreh Davoudi, William Detmold, Zhenghao Fu +6
Neutrinoless double-beta () decay is a heretofore unobserved process which, if observed, would imply that neutrinos are Majorana particles. Interpretations of the stringent e…
Update on the gradient flow scale on the 2+1+1 HISQ ensembles
Alexei Bazavov, Claude Bernard, Carleton E. DeTar +8
We report on the ongoing effort of improving the determination of the gradient flow scale on the (2+1+1)-flavor HISQ ensembles generated by the MILC collaboration. We compute the s…
