Connecting the Breit Frame to the Infinite Momentum Light Front Frame: How G_E turns into F_1

TL;DR

This paper demonstrates how the electric form factor G_E in the Breit frame transforms into the Dirac form factor F_1 in the infinite momentum frame, clarifying the connection between different reference frames in nucleon structure analysis.

Contribution

It provides a theoretical link showing that G_E becomes F_1 when boosted from the Breit to the infinite momentum frame, enhancing understanding of form factor transformations.

Findings

G_E in the Breit frame transforms into F_1 in the infinite momentum frame

The boost connects electromagnetic current matrix elements across frames

Clarifies the frame dependence of nucleon form factors

Abstract

We investigate the connection between the Breit and infinite momentum frames and show that when the nucleon matrix element of the time component of the electromagnetic current, which yields G_E in the Breit frame, is boosted to the infinite momentum (or light-front) frame, the quantity F_1 is obtained.
