# The Weak Force: From Fermi to Feynman

## TL;DR

This paper traces the historical development of the weak force theory from Fermi's initial model to the V-A theory, highlighting key experimental confirmations like parity violation and providing biographical and conceptual context.

## Contribution

It offers a chronological overview of the evolution of weak force theories, integrating historical, theoretical, and experimental perspectives with biographical insights.

## Key findings

- Confirmation of parity violation in weak interactions
- Development of V-A theory as the standard model component
- Historical synthesis of weak force understanding

## Abstract

Understanding of the weak force is traced from Fermi's theory of beta decay to the V-A theory of the mid 1950's. The theoretical suggestion and experimental confirmation of parity violation in the weak force is discussed. Topics are presented chronologically, leaving room for biographical sketches and introducing basic mathematical and physical concepts as needed.
