Which are the fundamental constituents of matter and which forces act upon them? Particle Physics is the subject that addresses the fundamental principles governing our world; forces and constituents. This understanding is formulated mathematically as theories (before called laws of nature). The subject evolves through experimental explorations, development of theories and models. Today our understanding is described by the theory the Standard Model which has an exceptional predictive power, but is incomplete. We explore the predictions of the Standard Model and seek a more complete understanding, i.e. beyond the Standard Model.
