elementary particle
Let an agent explain elementary particles and the Standard Model, describe fermions, bosons and their properties, present open questions and hypothesised particles with attribution, and support learning in physics.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain elementary particles and the Standard Model, describe fermions, bosons and their properties, present open questions and hypothesised particles with attribution, and support learning in physics.
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.
What it is for: Fundamental particles without substructure.
It can be explain the Standard Model; describe particles and properties; present open questions; support learning.
