Normalizing flows for all-orders QED corrections in lattice field theory
Nils Hermansson-Truedsson, Gurtej Kanwar
This work develops a framework to apply normalizing-flow transformations of field configurations for all-orders Quantum Electrodynamics (QED) corrections in lattice field theory. T…
Real radiative decays of heavy pseudoscalar mesons
Teseo San Jose, Yasumichi Aoki, Matteo Di Carlo +9
We report our ongoing lattice QCD study of radiative leptonic decays of the charged pseudoscalar mesons , , , and . We carry out our analysis on…
Isospin breaking corrections to the hadronic vacuum polarization with stochastic coordinate sampling
Mattia Bruno, Vera Gülpers, Nils Hermansson-Truedsson +3
In the recent Muon g-2 Theory Initiative white paper update, the hadronic vacuum polarization (HVP) contribution -- which dominates the theoretical uncertainty -- is evaluated as a…
On the Charm Contribution to the Muon Light-by-Light
Johan Bijnens, Nils Hermansson-Truedsson, Antonio RodrÃguez-Sánchez
We combine existing perturbative results to show that a precise analytic determination of the charm-quark contribution to the hadronic light-by-light (HLbL) part of the muon anomal…
The Pion Sum Rule beyond the Chiral Limit
Johan Bijnens, Nils Hermansson-Truedsson, Antonio RodrÃguez-Sánchez
The difference between the charged and neutral pion masses can be predicted from a well-known dispersion relation involving an infinite-energy integral over experimental data, the…
: a finite-volume QED action with redistributed spatial zero-momentum modes
Matteo Di Carlo, Maxwell T. Hansen, Nils Hermansson-Truedsson +1
We present a finite-volume QED action designed to improve the infinite-volume extrapolation of hadronic observables in precision lattice QCD+QED calculations. The action proposed i…
