Renormalization-guided cascade upscaling for lattice field generation
Anna Hasenfratz, Ethan T. Neil, Letizia Parato +1
We introduce a renormalization-group (RG) guided machine-learning algorithm for lattice field generation based on approximate inversion of an RG transformation. A ``perfect blockin…
Renormalization-guided inverse blocking for lattice field generation: construction and validation
Anna Hasenfratz, Ethan T. Neil, Letizia Parato +1
We propose an algorithm for generating lattice field configurations based on the approximate inversion of a renormalization-group blocking transformation. We optimize the blocking…
Comparing RM123 and non-perturbative QCD+QED approaches to the HVP with C-periodic boundary conditions
Anian Altherr, Isabel Campos, Alessandro Cotellucci +10
Isospin-breaking corrections to the HVP are among the leading sources of uncertainty in the Standard Model prediction of the muon . In recent work by the RC collabor…
Baryon masses with C-periodic boundary conditions
Anian Altherr, Isabel Campos, Roman Gruber +7
Isospin-breaking corrections pose a significant challenge to lattice simulations, both because of the splitting between the up and down quark masses and, in particular, the need to…
Comparing QCD+QED via full simulation versus the RM123 method: U-spin window contribution to
A. Altherr, I. Campos, A. Cotellucci +10
Electromagnetic corrections to hadronic vacuum polarization contribute significantly to the uncertainty of the Standard Model prediction of the muon anomaly, which poses conceptual…
Update on the isospin breaking corrections to the HVP with C-periodic boundary conditions
Anian Altherr, Isabel Campos, Alessandro Cotellucci +9
In the RC collaboration, we simulate lattice QCD+QED using periodic spatial boundary conditions to ensure that locality, gauge invariance, and translational invariance…
Error Scaling of Sea Quark Isospin-Breaking Effects
Anian Altherr, Isabel Campos, Alessandro Cotellucci +7
Sea-quark isospin-breaking effects (IBE) are difficult to compute since they require the evaluation of all-to-all propagators. However, the quest for high-precision calculations mo…
Partially connected contributions to baryon masses in QCD+QED
Anian Altherr, Isabel Campos, Alessandro Cotellucci +9
Full QCD+QED simulations allow to evaluate isospin breaking corrections to hadron masses. With the openQxD code, we are able to perform these simulations employing C-periodic bound…
-improved QCD+QED Wilson Dirac operator on GPUs
Anian Altherr, Isabel Campos, Jonathan Coles +13
Markov Chain Monte Carlo simulations of lattice Quantum Chromodynamics (QCD) are the only known tool to investigate non-perturbatively the theory of the strong interaction and are…
