Electromagnetic pion mass splitting using a Pauli-Villars-regulated photon propagator
Alessandro De Santis, Dominik Erb, Harvey B. Meyer
We present a lattice QCD calculation of the charged-neutral pion mass splitting at using a recently proposed framework based on…
Field-theoretic versus data-driven evaluations of electromagnetic corrections to hadronic vacuum polarization in
Volodymyr Biloshytskyi, Dominik Erb, Harvey B. Meyer +2
The Standard Model prediction of the muon increasingly depends on lattice QCD computations of the hadronic vacuum polarization (HVP), where the isospin-breaking (IB) effects…
Factorizing the position-space photon propagator in QED corrections to lattice QCD correlators
Dominik Erb, Harvey B. Meyer, Konstantin Ottnad
Electromagnetic corrections to the -point functions of lattice QCD can be evaluated using a position-space photon propagator defined in infinite volume. Here we address the comp…
Electromagnetic pion mass splitting using PV-regulated photon propagator
Alessandro De Santis, Dominik Erb, Harvey B. Meyer
Several hadronic observables are nowadays computed in lattice QCD with a sub-percent precision which requires the inclusion of strong isospin-breaking and electromagnetic effects.…
Isospin-violating vacuum polarization in the muon with SU(3) flavour symmetry from lattice QCD
Dominik Erb, Antoine Gérardin, Harvey B. Meyer +3
We compute the isospin-violating part of the hadronic-vacuum-polarization (HVP) contribution to the muon in lattice QCD at the SU-symme…
The isospin-violating part of the hadronic vacuum polarisation
Dominik Erb, Antoine Gerardin, Harvey B. Meyer +3
We present our calculation of the isospin-violating part of the hadronic vacuum polarisation (HVP) contribution to muon in lattice QCD at the symmetric…
