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…

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…

Sequestered String Models imply Split Supersymmetry

Michele Cicoli, Alessandro Cotellucci, Hajime Otsuka

Sequestering is a promising mechanism in 4D string models to reconcile high-scale inflation with low-energy supersymmetry. In this scenario the MSSM lives on branes at singularitie…
