The Standard Model of Particle Physics represents our current understanding of fundamental particles and their interactions within the framework of quantum field theory. This paper provides a comprehensive overview of the theoretical foundations, experimental validations, and theoretical extensions of the Standard Model. Beginning with an exploration of particle physics principles and the organizational structure of the Standard Model, the paper discusses experimental confirmations through particle accelerators and detectors, including landmark discoveries such as quarks, leptons, gauge bosons, and the Higgs boson. Furthermore, it examines the limitations of the Standard Model and explores theoretical extensions, such as supersymmetry and grand unified theories, which seek to address unresolved questions and advance our understanding of fundamental physics. The conclusion reflects on the current state of particle physics research and outlines future directions for exploring physics beyond the Standard Model.
