Moments of the Virtual Photon Structure Function
The photon structure function is a useful testing ground for QCD. It is perturbatively computable apart from a contribution from what is usually called the hadronic component of the photon. There have been many proposals for this nonperturbative part of the real photon structure function. By studying moments of the virtual photon structure function, we explore the extent to which these proposed...
متن کاملFirst Measurement of the Photon Structure Function
The first measurement of F γ 2,c is presented. At low x the measurement indicates a non-zero hadron-like component to F γ 2,c. At large x the measurement constitutes a test of perturbative QCD at next-to-leading order, with only mc and αs as free parameters, with a precision of O(40%). INTRODUCTION For about 20 years measurements of photon structure functions give deep insight into the rich str...
متن کاملThe photon structure function measurements from LEP
One of the most powerful tools to investigate the internal structure of quasi real photons is the measurement of photon structure functions in deep inelastic electron photon scattering at ee colliders. These measurements have by now a tradition of sixteen years since the first F γ 2 was obtained by PLUTO [1]. The LEP accelerator is a unique place for the measurements of photon structure functio...
متن کاملThe Photon Structure Function at Small-x
It is shown that recent small–x measurements of the photon structure function F γ 2 (x,Q) by the LEP–OPAL collaboration are consistent with parameter–free QCD predictions at all presently accessible values of Q. Recently the OPAL collaboration [1] at the CERN–LEP collider has extended the measurements of the photon structure function F γ 2 (x,Q ) into the small–x region down to x ≃ 10, probing ...
متن کاملThe Third Structure Function of the Photon
The moments of the photon's third structure function WY 3 are considered in quantum chromodynamics up to the next-to-the-leading order. The one-loop and two-loop anomalous dimensions of the relevant operators are calculated. Using these results, the part of the higher-order corrections is evaluated.
