The average fraction ($\equiv\langle{\cal Z}\rangle$) of jet momentum carried by the associated charged leading hadron has been determined in the reaction $p$ + $N\ \to\ h\sb1$ + $h\sb2$ + $X$ where $h\sb1$ and $h\sb2$ were two high P$\sb\bot$ hadrons, leading particles of two jets produced at high P$\sb\bot$. A 800 GeV/c proton beam and four nuclear targets: beryllium, aluminium, iron and tungsten were used. The data were taken at the Fermi National Accelerator Laboratory from November 1987-February 1988. / The detector was a double arm magnetic spectrometer, with two sampling calorimeters for real-time event selection and was capable of operating at a high interaction rate ($\approx$2.5 $\times$ 10$\sp6$ interactions per second). / $\langle{\cal Z}\rangle$, connected to the fragmentation process of the scattered partons in the QCD-parton model, has been determined as a function of the transverse momentum of the leading hadron and the cosine of the scattering angle of the leading hadron pair in the di-hadron C.o.M. system, for positive, negative and both sign charges of the leading hadron and for each target. / The fragmentation process was found to be independent of nuclear effects and the amount of nuclear matter crossed by the fragmenting parton. The $\langle{\cal Z}\rangle$ distributions agree with the QCD-parton model predictions for single independent parton-parton scattering and independent fragmentation process. / Agreement has also been found between these data and previous published ones obtained in a $pp$ collider experiment confirming the independence of the fragmentation process from nuclear effects in high P$\sb\bot$ interactions. / Source: Dissertation Abstracts International, Volume: 51-04, Section: B, page: 1882. / Major Professor: David A.
