The gamma* gamma* Total Cross Section and the BFKL Pomeron at the 500 GeV e+e- Collider

TL;DR

This paper estimates the gamma* gamma* total cross section at a 500 GeV e+e- collider using the BFKL Pomeron, highlighting its potential for testing QCD predictions with detectable event rates.

Contribution

It provides a numerical estimate of the gamma* gamma* cross section at high energy colliders based on the BFKL Pomeron, emphasizing experimental feasibility.

Findings

Substantial event rates are expected if small-angle scattered electrons are detected.

Measurement of the cross section offers a strong test of the BFKL Pomeron.

The study supports the potential for experimental validation of QCD models at future colliders.

Abstract

We present a numerical estimate of the $\gamma^* \gamma^*$ total cross section at the designed 500 GeV $e^+e^-$ Linear Collider, based upon the BFKL Pomeron. We find that the event rate is substantial provided electrons scattered under small angles can be detected, and a measurement of this cross section provides an excellent test of the BFKL Pomeron.
