Efficiently unquenching QCD+QED at O()
Tim Harris, Vera Gülpers, Antonin Portelli +1
We outline a strategy to efficiently include the electromagnetic interactions of the sea quarks in QCD+QED. When computing iso-spin breaking corrections to hadronic quantities at l…
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…
scattering as a step towards from Lattice QCD
Felix Erben, Matthew Black, Peter Boyle +7
Rare decays provide some of the most sensitive tests of the Standard Model and require precise and systematically improvable hadronic input from lattice QCD. F…
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…
Split-even approach to the rare kaon decay
Raoul Hodgson, Vera Gülpers, Ryan Hill +1
In recent years the rare kaon decay has been computed directly at the physical point. However, this calculation is currently limited by stochastic noise stemming from a light and c…
The long-distance window of the hadronic vacuum polarization for the muon g-2
T. Blum, P. A. Boyle, M. Bruno +15
We provide the first ab-initio calculation of the Euclidean long-distance window of the isospin symmetric light-quark connected contribution to the hadronic vacuum polarization for…
