| dc.description.abstract | 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 . | en_ZA |
