Model-independent QED corrections to photon structure-function measurements
E. Laenen, G. A. Schuler
We present the first calculation of QED radiative corrections to deep-inelastic electron-photon scattering in terms of those variables that are reconstructed in measurements of the…
Improving the equivalent-photon approximation in electron--positron collisions
Gerhard A. Schuler
The validity of the equivalent-photon approximation for two-photon processes in electron--positron collisions is critically examined. Commonly used forms to describe hadronic two-p…
Gamma-Gamma Physics at LEP2
P. Aurenche, G. A. Schuler, A. Bawa +41
This report is an overview of the gamma-gamma physics capabilities of LEP2, and covers the following topics: structure functions, equivalent photon approximation, tagging condition…
Low- and High-Mass Components of the Photon Distribution Functions
Torbjorn Sjostrand, Gerhard A. Schuler
Four new parton distributions of the photon are presented, with a description of theory choices, properties and applications.
On the non-perturbative part of the photon structure function
Gerhard A. Schuler
We discuss a dispersion relation in the photon mass and show how (in principle) model-independent constraints on the parton distribution functions of the photon, notably a momentum…
gamma-gamma and gamma-p Events at High Energies
Gerhard A. Schuler, Torbjorn Sjostrand
A real photon has a complicated nature, whereby it may remain unresolved or fluctuate into a vector meson or a perturbative q-qbar pair. Based on this picture, we previously presen…
