Baryons and the Borromeo

TL;DR

This paper discusses the complex behavior of light quarks within baryons, highlighting how dynamical effects in the Standard Model lead to significant mass variations and proposing a Borromean perspective on proton structure.

Contribution

It introduces a novel Borromean framework for understanding the structure and mass dynamics of baryons and their excited states within the Standard Model.

Findings

Dynamical effects cause light quarks to vary in mass within baryons.

Emerging experimental and theoretical insights into confinement mechanisms.

Proposal of a Borromean picture for proton and excited states.

Abstract

The kernels in the tangible matter of our everyday experience are composed of light quarks. At least, they are light classically; but they don't remain light. Dynamical effects within the Standard Model of Particle Physics change them in remarkable ways, so that in some configurations they appear nearly massless, but in others possess masses on the scale of light nuclei. Modern experiment and theory are exposing the mechanisms responsible for these remarkable transformations. The rewards are great if we can combine the emerging sketches into an accurate picture of confinement, which is such a singular feature of the Standard Model; and looming larger amongst the emerging ideas is a perspective that leads to a Borromean picture of the proton and its excited states.
