A Global Study of Photon-Induced Jet Production

TL;DR

This paper performs a comprehensive tuning of Monte Carlo models for photon-induced jet production, using data from HERA, LEP, and TRISTAN, and discusses implications for future linear colliders.

Contribution

It introduces a global tuning approach for Monte Carlo models of photon-induced jets, optimizing parameters like underlying event simulation and photon structure based on experimental data.

Findings

Certain model combinations are incompatible with the data.

Tuned models have implications for future collider experiments.

The study enhances the predictive accuracy of photon-jet simulations.

Abstract

We present results of a global tuning of general purpose Monte Carlo models to published measurements of photon-proton -> jets at HERA and photon-photon -> jets at LEP and TRISTAN. The principle free parameters in the tuning are the simulation of the underlying event and the choice of photon structure. Several combinations of models are ruled out by the data. Some consequences of the tuned models at a future linear collider are discussed.
