A Comparison of High Transverse Momentum Direct Photon and Neutral Pion Events in Negative Pion and Proton - Nucleus Collisions at 31.5-GeV Center-of-Mass Energy
- Michigan State U.
In 1988 experiment E706 at Fermilab wrote approximately 6 million triggered events to tape. The purpose of this was to measure the cross sections for high $$p \perp \pi^0$$ and single photon production. In addition, the cross sections were to be measured for proton and $$\pi^-$$ beams on a variety of nuclear targets. To achieve these goals the experiment had been furnished with a large liquid argon calorimeter. A magnetic spectrometer for studying the associated production of charged particles had been built as well. The purpose of this analysis is to compare the associated charged particle structure of high $$p\perp \pi^0$$ and direct photon events to see if they are indeed different. The current theory of hadron-hadron interactions, quantum chromodynamics, makes a number of predictions indicating that they are. The charged particles recoiling from a high $$p\perp \gamma$$ or $$\pi^0$$ trigger will be used to reconstruct the $$\pi^0$$ + jet and $$\gamma$$ + jet angular and invariant mass distributions for this study. Finally, the invariant mass distributions will be employed to study the gluon structure. functions of hadrons.
