An Introduction to QED and QCD
by N. J. Evans
Number of pages: 61
The aim of this course is to teach you how to calculate transition amplitudes, cross sections and decay rates, for elementary particles in the highly successful theories of Quantum Electrodynamics (QED) and Quantum Chromodynamics (QCD). Most of our work will be in understanding how to compute in QED.

We review the theory of hadronic atoms in QCD + QED based on a non-relativistic effective Lagrangian framework. We provide an introduction to the theory and describe several applications: meson-meson, meson-nucleon atoms and meson-deuteron compounds.

Quantum Chromodynamics, QCD, is the theory of quarks, gluon s and their interactions. The aim of these lectures is to provide students with an introduction to some of the core concepts and methods of QCD that are relevant in an LHC context.

The authors develop the perturbative framework for the calculation of hard scattering processes. The text provides both a rigorous development of the formalism of hard scattering of quarks and gluons and an intuitive understanding of the physics.

Important progress in understanding the behavior of hadronic matter at high density has been achieved recently. We discuss the phase diagram of QCD as a function of temperature and density, and close with a look at possible astrophysical signatures.
