High Transverse Momentum Hadron Production in 400 and 800 Gev/c Proton-Nucleon Collisions.

Results of high transverse momentum hadron production in 400 Gev / c proton-proton and proton-deuteron and 800 Gev / c proton-proton collisions are presented in this dissertation. The transverse momentum range of the data was from 5.2 to 9.0 Gev / c for the 400 Gev / c collisions and from 3.6 to 11.0 Gev / c for the 800 Gev / c collisions; the data were centered around the proton-nucleon center -of-momentum production angle of 90^circ . Single pion invariant cross sections and particle ratios were measured at both energies and the unlike-sign dihadron correlation function was measured at the higher energy. The results are compared to previous experiments and the Lund model.
