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.

Application of Quantum Field Theory

The Bogomolny Bound for scalar quantum field theory in two dimensions is analyzed and the generalization of this result to fractional powers of the differential operator is analyzed.

Essential Fierz identities for a fermionic field

: For a single fermionic field, an interpretation of the Fierz identities (which establish relations between the bilinear field observables) is given. They appear closely related to the algebraic class

Quantum Field Theory in de Sitter spacetime

In this paper we will analyse quantum field theory on de Sitter spacetime. We will analyse a general scalar and vector field theory on de Sitter spacetime. This is done by first calculating these

Introduction and Theoretical Background

The neutrino was first proposed to save energy conservation in nuclear \(\beta \) decay. By 1914, Chadwick had shown that the \(\beta \) energy spectrum was continuous [1], but \(\beta \) decay was

Perturbative Quantum Gravity on de Sitter Spacetime

We will analyse perturbative quantum gravity on de Sitter spacetime. We propose a new type of inner product for modes on de Sitter spacetime. This inner product is used to mode decompose

Development of a new superfluid helium ultra-cold neutron source and a new magnetic trap for neutron lifetime measurements

The development of an ultra-cold neutron (UCN) source at the Institut Laue-Langevin (ILL) based on super-thermal down-scattering of a cold neutron beam in superfluid helium is described. A continuous

Inner Product in Quantum Field Theory

In this paper we will analyse the inner product for a general tensor field theory. We will first analyse a generalized inner product for scalar field theories. Then we will use it to construct a

Gauge Theories on de Sitter Spacetime

In this paper we will analyse the inner product for gauge theories in de Sitter spacetime. This will be done by analysing an Euclidean version of the de Sitter metric. Thus, the de Sitter metric will

Weak Interactions of Leptons and Quarks

In recent years, the study of weak interaction and its relationship with the other fundamental interactions of nature has progressed rapidly. Weak interactions of leptons and quarks provides an

The Physics of the Standard Model and Beyond

This book provides a unified description of elementary particle interactions and the underlying theories, namely the Standard Model and beyond, and conveys the excitement of particle physics, centering upon experimental observations and a variety of ideas for their interpretation.
