This thesis describes a study of the production of high transverse momentum direct photons and [pi][sup 0] mesons by proton beams at 530 and 800 GeV/c and [pi][sup -] beams at 515 GeV/c incident on beryllium, copper, and liquid hydrogen targets. The data were collected by Fermilab experiment E706 during the 1990 and 1991-92 fixed target runs. The apparatus included a large, finely segmented lead and liquid argon electromagnetic calorimeter and a charged particle spectrometer featuring silicon strip detectors in the target region and proportional wire chambers and drift tubes downstream of a large aperture analysis magnet. The inclusive cross sections are presented as functions of transverse momentum and rapidity. The measurements are compared with next-to-leading order perturbative QCD calculations and to results from previous experiments.

A search for pairs of high p/sub T/ prompt photons produced in hydrogen by a 280 GeV/c incident /pi//sup -/ beam has been carried out using a fine-grained electromagnetic calorimeter and the Omega spectrometer at the CERN SPS. Clear evidence for the existence of such events is found with a six standard deviation signal for p/sub T/> 3.0 GeV/c. The cross sections are consistent with beyond leading order QCD calculations. A discussion on the determination of [alpha]/sub s/ is also presented. 18 refs., 7 figs., 7 tabs.
