The Hadronic Final States in Deep Inelastic $eγ$ Scattering at a Future e^+e^- Linear Collider
Abstract
Description
Energy flow distributions from tagged $γγ$ events generated with HERWIG are presented for $E_{beam} = 45.6$ GeV (LEP1) and $E_{beam} = 175$ GeV (top-quark threshold at a future e^+e^- Linear Collider). They have very similar shapes regardless of the beam energy. Using the present knowledge of the LEP $F_2^γ$ 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 $γγ$ Monte Carlos. Such models are relied upon to extract $F_2^γ$ from the data, and hence understanding the forward region well may be crucial in the determination of whether or not a low-$x$ rise exists in the photon structure function.
