Sakata model of hadrons revisited

TL;DR

This paper revisits the Sakata model of hadrons, proposing new potentials between sakatons that better explain particle stability and masses, challenging the view that the model predicts too many unobserved particles.

Contribution

It introduces a set of pairwise potentials between sakatons and antisakatons, providing a better match with observed hadron properties and addressing previous criticisms.

Findings

Potentials describe stability and masses of hadrons accurately.

Model aligns well with experimental observations.

Challenges the notion that Sakata model predicts unobserved particles.

Abstract

46 years ago the quark model replaced the Sakata model as the standard explanation of the hadron structure. The major alleged defect of the Sakata model was its prediction of just too many types of particles, which have not been seen in experiments. However, this allegation was made without detailed consideration of the forces acting between sakatons. In this article we suggest a set of pairwise sakaton-sakaton and sakaton-antisakaton potentials that describe stability and masses of strongly interacting elementary particles in a good agreement with observations.
