Proton charge radius and the perturbative quantum electrodynamics

TL;DR

This paper suggests that the proton charge radius discrepancy can be addressed by relaxing the assumption of purely perturbative quantum electrodynamics inside the proton, potentially resolving longstanding measurement conflicts.

Contribution

It introduces a non-perturbative perspective on QED within the proton to explain the charge radius discrepancy.

Findings

Proposes weakening the perturbative assumption in QED inside the proton.

Indicates potential resolution of the proton radius puzzle.

Challenges conventional perturbative approaches in proton structure analysis.

Abstract

We argue that the proton charge radius conundrum can be resolved by weakening the assumption of perturbative formulation of quantum electrodynamics within the proton
