Nonstrange Baryon Properties From One-Gluon Exchange And Linear Confinement Between Quarks , Mark Linden Kiefer

#### Nonstrange Baryon Properties From One-Gluon Exchange And Linear Confinement Between Quarks , Mark Linden Kiefer

*Retrospective Theses and Dissertations*

We present a model of the quark structure of nonstrange baryons. We use quasi-quarks whose masses are roughly 1/3 the proton mass and which interact via one-gluon exchange and linear confining two-body potentials. The model is semirelativistic in that the quark kinetic energies and the one-gluon exchange potential include the lowest order, nonrelativistic terms plus the first order relativistic corrections. The three quark Hamiltonian is diagonalized in a harmonic oscillator basis using all states up to 6(omega) of excitation energy. The basis states have the center of mass motion explicitly factored out and are overall antisymmetric in the ...

#### A Local Approximation Of A Qcd-Inspired Nucleon-Nucleon Interaction , Deborah Reed-Margetan

*Retrospective Theses and Dissertations*

There have been several attempts to understand the nature of the nucleon-nucleon interaction on the basis of the quark structure of the nucleon. In this work, the potential model approach is pursued. In particular, this project expands upon work done by P. D. Morley, D. L. Pursey, and S. A. Williams. They started with a basic interaction between quarks which was the sum of a phenomenological confining potential for quark confinement and a one-gluon-exchange potential inspired by QCD. This model led naturally to a nonlocal nucleon-nucleon interaction. In this thesis, a consistent local approximation to this nonlocal potential is presented ...
