Massive Degeneracy and Goldstone Bosons: A Challenge for the Light Cone

TL;DR

This paper discusses the difficulties of the light front formalism in handling Goldstone symmetries and challenges the idea that hadron condensates explain Goldstone phenomena.

Contribution

It critically examines the light front formalism's limitations and refutes the role of hadron condensates in Goldstone symmetry breaking.

Findings

Light front formalism faces fundamental issues with Goldstone bosons.

Hadron condensates do not explain Goldstone phenomena as previously thought.

The paper highlights the need for alternative approaches to Goldstone symmetry in light-front theories.

Abstract

Wherein it is argued that the light front formalism has problems dealing with Goldstone symmetries. It is further argued that the notion that in hadron condensates can explain Goldstone phenomena is false.
