Lagrange triangle quark model of the proton

摘要

A model of three quarks at the corners of an Lagrange equilateral tri- angle is used to describe a nucleon. Kipole fits to the electromagnetic form factors are used to require an exponential radial dependence for the wave function. This guide from experiment leads to a linear confining potential using the Dirac equation to describe the dynamics of the model. His model can reproduce the proton magnetic moment, axial charge, Roper resonance energy, and the size of the dipole fits to the electromagnetic form factors, but not all simultaneously.
