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.

Threshold Corrections in Precision LHC Physics: QED otimes QCD [PDF]

International Journal of Modern Physics A, 2004
With an eye toward LHC processes in which theoretical precisions of 1 percent 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 Study of Positronium: Testing Bound State QED Theory [PDF]

International Journal of Modern Physics A, 2003
As an unstable light pure leptonic system, positronium is a very specific probe atom to test bound state QED. In contrast to ordinary QED for free leptons, the bound state QED theory is not so well understood and bound state approaches deserve highly ...

Precision study of positronium and precision tests of the bound state QED

, 2002
Despite its very short lifetime positronium provides us with a number of accurate tests of the bound state QED. In this note a brief overview of QED theory and precision experiments on the spectrum and annihilation decay of the positronium atom is ...

The longitudinal structure function in the presence of QED effects

Physics Letters B, 2021
The highest precision for theoretical predictions at the high LHC energy requires the calculation of parton distribution function (PDFs) and the structure functions which include heavy quarks that include perturbative QCD and QED corrections.

Resolving charged hadrons in QED — gauge invariant interpolating operators

Journal of High Energy Physics, 2022
Standard interpolating operators for charged mesons, e.g. J B = b ¯ $$ \overline{b} $$ iγ 5 u for B − , are not gauge invariant in QED and therefore problematic for perturbative methods.

The physics potential of a reactor neutrino experiment with Skipper CCDs: measuring the weak mixing angle

Journal of High Energy Physics, 2021
We analyze in detail the physics potential of an experiment like the one recently proposed by the vIOLETA collaboration: a kilogram-scale Skipper CCD detector deployed 12 meters away from a commercial nuclear reactor core.
