“The Standard Model of elementary particles is a theoretical framework that describes the fundamental building blocks of matter and their interactions. It is the best-tested physics theory to date, and explains the behavior of all known particles and their interactions. It is used to predict the existence of new particles, and has been found to be consistent with a range of experimental results.
“The Standard Model is built on the mathematical framework of quantum field theory, and is composed of two main components: matter particles, which are the building blocks of all known matter, and force particles, which mediate the interactions between matter particles. The matter particles include the quarks and leptons, which make up the atoms of everyday matter, and the gauge bosons, which are the particles that mediate the forces of nature between matter particles. The gauge bosons are the photon, the W and Z bosons, and the gluon.
“The Standard Model is the most successful theory of particle physics, and has been tested and verified at the highest energies so far achievable in particle accelerators. It is the cornerstone of modern particle physics, and its predictions have been tested with high precision in particle colliders and experiments. The Standard Model is expected to remain valid at higher energies, and is the basis for ongoing and future research into new particles and forces of nature.”
I then prompted it to add something that was conspicuously missing:
“The most important particle of the Standard Model is the Higgs boson, which was discovered in 2012 at the Large Hadron Collider. The Higgs boson is responsible for giving particles their mass and is the only particle predicted by the Standard Model that had not yet been discovered. Its discovery was a major milestone in particle physics and marked the completion of the Standard Model.”
