The tower of states model: An exploration of the effect of higher-order resonances on the nucleon-nucleon system
Herbst, Kelly Ann
Herbst, Kelly Ann
Abstract
A new model of the nucleon-nucleon interaction which employs a tower of charged nucleon resonances is explored in the simplest possible framework. The model is manifestly covariant, relativistic, analytically solvable, and gauge invariant. Three variants on the model are presented: one employs a tower consisting of the proton only, the other two have a three-member tower consisting of the proton, the Roper, and the D{dollar}\sb{lcub}13{rcub}{dollar}. Nucleon-nucleon data below 350 MeV are well described by these tower models, and the deuteron wave function and form factor are also calculated. Models containing large inelasticities are also explored. A complete presentation of the development of the model is given, including a calculation of the inclusive deuteron electrodisintegration cross section, followed by current results and future prospects.
