Feynman diagram

n.
A diagram used in quantum electrodynamics and quantum chromodynamics to help describe and visualize the possible interactions between particles. Fermions are represented with straight lines, and bosons with wavy lines. Points of intersection indicate an interaction between the particles.

[After Richard Phillips Feynman.]

In other words, the volume focuses on the interpretation of experimental data in terms of the basic properties and interactions of quarks, leptons, and hadrons, making extensive use of symmetry principles and Feynmann diagrams. Other topics discussed include space-time symmetries, the quark model of hadrons, quantum chromodynamics and jet physics, the weak interaction (including its unification with the electromagnetic interaction and CP violation and other related symmetries), and some important open questions beyond the standard model that are currently being investigated.
