Renormalon subtracted nonrelativistic QCD for heavy hadron systems
Benoît Assi, Andreas S. Kronfeld, Simon Vaiva +1
We present a renormalon-subtracted formulation of potential nonrelativistic QCD (pNRQCD) for precision spectroscopy of heavy hadron systems, combining variational and Green's funct…
Wilson loops with neural networks
Verena Bellscheidt, Nora Brambilla, Andreas S. Kronfeld +1
Wilson loops are essential objects in QCD and have been pivotal in scale setting and demonstrating confinement. Various generalizations are crucial for computations needed in effec…
Strong coupling constant from the 1-loop improved static energy
Viljami Leino, Alexei Bazavov, Nora Brambilla +8
The static energy is an excellent observable for extracting the strong coupling on the lattice. For short distances, the static energy can be calculated both on the lattice…
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…
