Standard Model Particle Explorer

The Standard Model of particle physics is the best-tested theory in science: every quark, lepton and force-carrying boson ever directly observed fits into one compact table, organized by generation and interaction type. This simulator lays that table out in 3D — 6 quarks and 6 leptons arranged by generation on the left, the photon, gluon, W, Z and Higgs bosons clustered on the right — and pairs it with a live simplified particle-collision demo. Filter by particle family, scrub through generations to compare masses, and turn up the collision energy past roughly 125 GeV to watch a Higgs boson get produced and decay, the same discovery ATLAS and CMS made at CERN in 2012.
