The angular distribution of hadron pairs produced in the interaction of 800 GeV/c protons on targets of aluminium, beryllium, iron and tungsten have been measured, inferring the underlying dynamics of parton-parton scattering in these interactions. The transverse momentum hadron pairs with p$\sb{\rm T} <$ 2.0 GeV/c are studied in three charge states, (+ +), (+ $-$), ($- -$) covering the dihadron mass range of 7 to 15 GeV/c$\sp2$ and scattering angles up to cos $\theta\sp\*$ = 0.50. While the parton-parton angular distributions are shown to be independent of the target type, a small dependence on the charge state of the distributions is observed. These results are found to be generally consistent with the results of leading log QCD calculations. Unlike-sign charge state distributions for this experiment are found to deviate from low x dijet results as expected, and are found to be consistant with neutral dipion production results. / The cross section as a function of the parton-parton scattering angle for the three charge states is shown to vary linearly with the value of the atomic weight. The ratio of the cross sections for different charge states as a function of the parton-parton scattering angle is also found to compare favorably with the predictions of leading log QCD calculations. / Source: Dissertation Abstracts International, Volume: 52-08, Section: B, page: 4269. / Major Professor: Vasken Hagopian. / Thesis (Ph.D.)--The Florida State University, 1991.
