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…
