-Bosons are particles that mediate [[fundamental forces]] in the universe. Unlike '''fermions''', multiple bosons <u>can</u> <u>occupy the same quantum state</u>. There are several types of bosons, each associated with a fundamental force:
-* '''Photons''' (γ) are responsible for carrying the <u>electromagnetic force</u>, which governs interactions between electrically '''charged''' particles. They are massless and travel at the speed of light. Photons transmit (or broadcast the passage of) electromagnetic radiation. The photon is its own '''antiparticle''', because it is electrically neutral.
-* '''Gluons''' (g) mediate the <u>strong nuclear force</u>, which binds quarks together within '''hadrons''' (such as in '''mesons''' like protons and neutrons). The SNF is the fundamental force that fuses parts of atomic nuclei together. Gluons carry the '''color charge''' of the SNF and come in combinations that are their own antiparticles, as well as combinations that have distinct antiparticles. There are eight types of gluons in [[Quantum Chromodynamics|quantum chromodynamics]] (QCD), and their antiparticles are defined by color and '''anticolor''' charges.
-* '''Bosons''' (W+, W-, Z0) are responsible for mediating the <u>weak nuclear force</u>, which governs certain types of particle interactions like '''radioactive decay'''. The WNF is involved in processes that change one type of '''quark''' into another and is crucial for the energy production of stars. The W+ is the antiparticle of the W− and vice versa; they are charged bosons, and their charge determines the distinction between particle and antiparticle. The Z boson is neutral and is its own antiparticle.
-** '''Higgs Boson''' (H0) is associated with the <u>Higgs field</u>, which gives particles '''mass'''. Its discovery confirmed the existence of the '''Higgs mechanism''', a fundamental aspect of the <u>Standard Model</u>. The Higgs boson is electrically neutral and has no quantum numbers that would differentiate it from an opposite, so it is considered its own antiparticle.
