The aim of this book is to present fundamental concepts in particle physics.

This includes topics such as the theories of quantum electrodynamics, quantum chromodynamics, weak interactions, Feynman diagrams and Feynman rules, important conservation laws and symmetries pertaining to particle dynamics, relativistic field theories, gauge theories, and more.

In addition to explaining the underlying theories in a detailed manner, we provide a number of examples that will illustrate the formalisms "in action".

J.L. holds since 2013 a position as Professor of Physics at the Norwegian University of Science and Technology. His research is focused on theoretical quantum condensed matter physics and he has received several prizes for his Ph.D work on the interplay between superconductivity and magnetism. He has also received the American Physical Society ”Outstanding Referee” award, selected among over 60.000 active referees. In teaching courses such as Classical Mechanics and Particle Physics for both undergraduate and graduate students, he has invariably received high scores from the students for his pedagogical qualities and lectures.
