Conclusions

A critical aspect of measuring F₂^$\gamma$ is to ensure that the Monte Carlos used for the unfolding procedure correctly model the final state. Energy flow distributions from tagged $\gamma$$\gamma$ events have very similar shapes regardless of the beam energy in e⁺e^- collisions. Using this fact, and the present knowledge of the LEP F₂^$\gamma$ analyses, it is forseen that the understanding of the hadronic response of the forward region of the LC detector is vital to the development of the final state models in $\gamma$$\gamma$ Monte Carlos. This could be especially important in the determination of whether or not a low-x rise exists in the photon structure function.
