    Weak Interactions and Electroweak Theory Notes 1: Weak interactions of leptons Introduction This part of the course is about weak interactions. You already know quite a lot about the weak force, -decay of nuclei, the Wand the Z, avour changing interactions and the interactions of neutrinos. These lectures will consolidate this and introduce a File Size: 95KB. Modern Particle Physics Online Resources. This note covers the following topics: The Dirac Equation, Interaction by Particle Exchange, Electron Positron Annihilation, Electron Proton Elastic Scattering, Deep Inelastic Scattering, Symmetries and the Quark Model, Quantum Chromodynamics, V-A and the Weak Interaction, Leptonic Weak Interactions, Neutrino Oscillations, Weak Interactions of Quarks.

In my physics textbook, while talking about the scope of physics, it mentions the four fundamental forces of nature which are Gravitational force, Electromagnetic force, Strong Nuclear force and Weak Nuclear force, of these the most astonishing one I feel is the weak nuclear force. My book states that it is responsible for β -decay and other kinds of radioactivity.

I can recommend this book to those aiming for a broad working knowledge of the essentials of particle theory. It is a book to which I shall continue to.

In the late s, weak interactions were well described by the Fermi current current theory and there was no compelling experimental reason to want to change it: the problems were theoretical.

Introduction At present there are reasons to expect that the correct formulation of weak interaction theory may yet undergo an essential evolution.

The latter may take different directions (the hypothesis of an intermediate meson, etc.) but the ultimate result must evidently be an answer to the question: why the non-conservation of parity is characteristic of weak rather than strong : M.A.

The "standard model" of unified electroweak interactions is thoroughly discussed including current developments. The final chapter contains an introduction to unified theories of strong and electroweak interactions. • Weak interactions are mediated by the “intermediate bosons” W± and Z0 • Just as the EM force between two current carrying wires depends on the EM current, the weak interaction is between two weak currents, describing the flow of conserved weak charge, g j ∝ ψ* ψ • Two types of interactions: – CC (charged current).

This book comprises an introduction to the theory of the weak interaction of elementary particles. The author outlines the current situation in weak interaction theory and discusses the prospects for the coming decade. Fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.

All the known forces of nature can be traced to these fundamental interactions. The fundamental interactions are characterized on the basis of the following four criteria: the types of particles. Current - current theory •We can also describe weak interactions in terms of the interactions of two "currents".

In β-decay one current converts a neutron into a proton, and the other creates an electron and its antineutrino (absorbs or destroys neutrino). •For simplicity consider leptonic reactions which File Size: 1MB.
