THRESHOLD CORRECTIONS IN PRECISION LHC PHYSICS: QED⊗QCD [PDF]
International Journal of Modern Physics A, 2005 With an eye toward LHC processes in which theoretical precisions of 1% are desired, we introduce the theory of the simultaneous YFS resummation of QED and QCD to compute the size of the expected resummed soft radiative threshold effects in precision studies of heavy particle production at the LHC.

Coloring mixed QCD/QED evolution [PDF]
SciPost Physics, 2022 Parton showers are crucial components of high-energy physics calculations. Improving their modelling of QCD is an active research area since shower approximations are stumbling blocks for precision event generators.

Towards Precision Spectroscopy of Antiprotonic Atoms for Probing Strong-field QED [PDF]
Proceedings of International Conference on Exotic Atoms and Related Topics and Conference on Low Energy Antiprotons — PoS(EXA-LEAP2024)PAX (antiProtonic Atom X-ray spectroscopy) is a new experiment with the aim to test strong-field quantum electrodynamics (QED) effects by performing high-precision x-ray spectroscopy of antiprotonic atoms. By utilizing advanced microcalorimeter detection techniques and a low-energy antiproton beam provided by the ELENA ring at CERN, gaseous targets ...

Muonic-Atom Spectroscopy and Impact on Nuclear Structure and Precision QED Theory [PDF]
, 2022 Recent progress in laser and x-ray spectroscopy of muonic atoms offers promising long-term possibilities at the intersection of atomic, nuclear and particle physics. In muonic hydrogen, laser spectroscopy measurements will determine the ground-state hyperfine splitting (HFS) and additionally improve the Lamb shift by a factor of 5.

$\alpha_{QED, eff}$(s) for precision physics at the FCC-ee/ILC [PDF]
, 2019 Discovering “Physics behind precision” at future linear or circular colliders (ILC/FCC projects) requires improved SM predictions based on more precise input parameters. I will review the role αQED, eff at future collider energies and report on possible progress based on results from low energy machines.

PHOTOS Monte Carlo for precision simulations of QED in decays [PDF]
Proceedings of XI International Workshop on Advanced Computing and Analysis Techniques in Physics Research — PoS(ACAT), 2009 Because of properties of QED, the bremsstrahlung corrections to decays of particles or resonances can be calculated, with a good precision, separately from other effects.
