An Algebraic Model of Nucleon Systems with Rules of Isospin Superselection

Abstract

A simple algebraic model with rules of isospin superselection is formulated and tested on few-nucleon systems. It is shown that physically obtainable states corresponding to the bound states of these nucleons can be gained by applying symmetrical monoidal C* categories whose objects are G-modules, and whose morphisms are G-invariant homomorphisms.
