The Standard Model of Particle Physics is the crowning achievement of the last decade of quantum mechanic research. The model categorizes and describes all of the fundamental (indivisible) particles discovered. Leptons, particles such as the electron, muon, and tau, all constitute a portion of an atom at varying levels of energy. Each of the three base leptons has a corresponding neutrino, a lepton that results from high energy nuclear decays, and aids in the destruction of a neutron into a proton and electron in said nuclear decays. The leptons, along with six types of quarks that compose protons and neutrons at different energy levels and particle collisions, are classified as fermions. The Bosons, a second classification of fundamental particle, carries the forces that govern each fermion. Each particle transmits or "carries" a different force- gravity, electromagnetism, strong, or weak. The Higgs Boson, however, acts in a much different way, as it gives matter mass by forming a field that is depressed by massive objects.
