Testing QCD in Photon-Photon Interactions
Stefan Soldner-Rembold (Freiburg University)
TL;DR
This paper discusses how high-energy photon-photon interactions, dominated by quantum fluctuations, serve as a testing ground for Quantum Chromodynamics (QCD) using data from electron-positron collisions at LEP.
Contribution
It highlights the use of LEP electron-positron collision data to study photon structure and test QCD predictions.
Findings
Photon interactions at high energies reveal photon structure.
Quantum fluctuations into fermion-antifermion pairs and vector mesons are dominant.
LEP data provides a valuable testing ground for QCD theories.
Abstract
At high energies photon-photon interactions are dominated by quantum fluctuations of the photons into fermion-antifermion pairs and into vector mesons. This is called photon structure. Electron-positron collisions at LEP are an ideal laboratory for studying photon structure and for testing QCD.
