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…
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…
Multigrid low-mode averaging
Roman Gruber, Tim Harris, Marina Krstic Marinkovic
We develop a generalization of low-mode averaging in which the number of low quark modes of the Dirac operator required for a constant variance reduction can be kept independent of…
Variance reduction via deflation with local coherence
Roman Gruber, Tim Harris, Marina Krstić Marinković
In large enough volumes, translation-averaging for quark-line connected diagrams reduces the variance inversely proportional to the volume. Stochastic estimators which implement tr…
Strange and charm contributions to the HVP from C* boundary conditions
Anian Altherr, Lucius Bushnaq, Isabel Campos +12
We present preliminary results for the determination of the leading strange and charm quark-connected contributions to the hadronic vacuum polarization contribution to the muon's g…
Hadronic vacuum polarization with C* boundary conditions
Anian Altherr, Roman Gruber, Lucius Bushnaq +12
We present a progress report on the calculation of the connected hadronic contribution to the muon g-2 with C* boundary conditions. For that purpose we use a QCD gauge ensemble wit…
Tuning of QCD+QED simulations with C boundary conditions
Anian Altherr, Lucius Bushnaq, Isabel Campos +10
We give an update on the ongoing effort of the RC collaboration to generate fully dynamical QCD+QED ensembles with C boundary conditions using the openQD co…

Anian Altherr, Lucius Bushnaq, Isabel Campos +10
We give an update on the ongoing effort of the RC collaboration to generate fully dynamical QCD+QED configurations with C boundary conditions using the openQ$^\star…
Performance optimizations for porting the openQD package to GPUs
Roman Gruber, Anton Kozhevnikov, Marina Krstić Marinković +2
OpenQD code has been used by the RC collaboration for the generation of fully dynamical QCD+QED gauge configurations with C boundary conditions. In this tal…
