A Dissertation Submitted to the Faculty of Science University of the Witwatersrand, Johannesburg for the Degree of Master of Science. Johannesburg 1985 / The success of bag models In hadron physics seems to imply that such models should be taken seriously as an approximation to QCD. In this belief a two-centre harmonic oscillator " bag " is utilised to describe kaon-proton scattering. An adiabatic approximation of the resulting system leads to a coupled channels formulation of the scattering problem . Because of Its complexity a solution of the gluon coupling inside a double-centred bag was not attempted; this turns out to be the most important interaction term and is simply parametrised. Even though all potentials are approximated by square wells and a variety of other approximations are made, a fair fit to the experimental phase shift data is obtained. It seems that the " bare " masses of the unstable baryons differ appreciably from positions of the experimental resonances .

The microscopic, momentum space, optical potential description of spin 1/2 x 1/2 scattering is extended to include the coupling of the singlet-triplet spin channels and the exact handling of the Coulomb force. Computing performance in constructing the optical potential and in solving the coupled-channels Lippmann-Schwinger equations is enhanced by parallelization via the PVM library. Cross sections and spin observables are predicted for p - ����C and p - ��He elastic scattering at 500 MeV. The complete set of nucleon-trinucleon reactions is calculated to investigate the sensitivity of these reactions to charge-symmetry breaking effects. / Graduation date: 1996
