QED challenges at FCC-ee precision measurements [PDF]
European Physical Journal C: Particles and Fields, 2019 The expected experimental precision of the rates and asymmetries in the Future Circular Collider with electron–positron beams (FCC-ee) in the center of the mass energy range 88–365 GeV considered for construction in CERN, will be better by a factor 5–200.

QED at NNLO and beyond for precision experiments [PDF]
Proceedings of 16th International Symposium on Radiative Corrections: Applications of Quantum Field Theory to Phenomenology — PoS(RADCOR2023), 2023 Low-energy experiments allow for some of the most precise measurements in particle physics, such as $g-2$. To make the most of these experiments, theory needs to match the experimental precision.

QED with massive photons for precision physics: zero modes and first result for the hadron spectrum [PDF]
Proceedings of The 38th International Symposium on Lattice Field Theory — PoS(LATTICE2021), 2022 The current precision reached by lattice QCD calculations of low-energy hadronic observables, requires not only the introduction of electromagnetic corrections, but also control over all the potential systematic uncertainties introduced by the lattice ...

Probing High-Energy Physics with High-Precision QED Measurements [PDF]
HEP-MAD '01, 2002 I summarize our self-contained determinations of the lowest order hadronic contributions to the anomalous magnetic moments a_{\mu,\tau} of the muon and tau leptons, the running QED coupling \alpha(M_Z) and the muonium hyperfine splitting \nu.

From theory to precision modelling of strong-field QED in the transition regime [PDF]
Journal of Physics: Conference Series, 2021 The combination of energetic electron beams, delivered from conventional accelerators at a high repetition rate, and ultraintense lasers, makes it possible to perform precision measurements of strong-field QED.

PHOTOS Monte Carlo: a precision tool for QED correctionsin Z and W decays [PDF]
The European Physical Journal C, 2005 .We present a discussion of the precision for the PHOTOS Monte Carlo algorithm, with improved implementation of QED interference and multiple-photon radiation. The main application of PHOTOS is the generation of QED radiative corrections in decays of any
