What it is Filled
A particle with no known substructure, the basic constituent of matter and carrier of forces in the Standard Model of particle physics, comprising the fermions, namely quarks and leptons such as electrons and neutrinos, and the bosons, namely the photon, gluons, the W and Z bosons that mediate the weak force, and the Higgs boson, together with hypothesised particles such as the axion and graviton; elementary particles are studied at accelerators and in cosmic rays and described by quantum field theory.
Why it exists Filled

Identity and identifiers required Filled
- Vercy registry: vr.tr.elementary-particle
- Wikidata: Q43116 (https://www.wikidata.org/wiki/Q43116)
Direct properties required Filled
- Rest mass: kg - Rest mass is determined or constrained from energy and momentum measurements and depends on the particle species.
- Electric charge: C - Electric charge is inferred from electromagnetic interactions and is characteristic of the particle species.
- Intrinsic spin angular momentum: hbar - The spin quantum number is inferred from scattering, spectroscopy and angular distributions rather than from physical rotation.
- Mean lifetime: s - Mean lifetime is inferred from decay statistics, while particles without observed decay are assigned experimental lower bounds where applicable.
Recognition required Filled
