Precision tests of QED
VERIFYING QUANTUM ELECTRODYNAMICS VIA MULTIPLE MEASUREMENTS OF THE FINE-STRUCTURE CONSTANT
Precision tests of quantum electrodynamics; Precision tests of qed; Tests of electromagnetism
Quantum electrodynamics (QED), a relativistic quantum field theory of electrodynamics, is among the most stringently tested theories in physics. The most precise and specific tests of QED consist of measurements of the electromagnetic fine-structure constant, α, in various physical systems.
