Exploring Confinement with Spin

TL;DR

This paper discusses how confinement in gauge theories and spin-dependent experiments challenge fundamental assumptions of quantum mechanics and strong interaction physics, highlighting potential violations of established bounds like the Soffer bound in QCD.

Contribution

It introduces the idea that confinement can violate the completeness of asymptotic states and suggests that experimental violations of the Soffer bound could revolutionize understanding of strong interactions.

Abstract

A confining gauge theory violates the completeness of asymptotic states held as foundation points of the $S$-matrix. Spin-dependent experiments can yield results that appear to violate quantum mechanics. The point is illustrated by violation of the Soffer bound in $QCD$. Experimental confirmation that the bound is violated would be a discovery of immense importance, sweeping away fundamental assumptions of strong interaction physics held for the past 50 years.
