Production of Large-Transverse-Momentum Jets in Photon-Photon Collisions

Abstract

We predict a new source of jet structure in $e^{+}{e}^{-}$ colliding-beam experiments arising from photon-photon collisions. These jets are produced with a sizable fraction of the total observable hadronic rate and have unmistakable signatures. Observations of these jets would provide important tests of the contributions of three classes of hard-scattering mechanisms: quark exchange in $\gamma \gamma \to q\overline{q}$, gluon exchange in $\mathrm{qq}$ and $q\overline{q}$ scattering, and constituent-interchange processes with a characteristic ${p_{\perp }}^{-6\mathrm{}}$ behavior.
