fundamental particle

He claims the objects of quantum theory, such as a photon, electron, or other fundamental particle, are nothing more than the properties they exhibit when interacting with—in relation to—other objects.

The Standard Model of particle physics describes the fundamental particles which make up the universe, and the forces that act between them.

Notable exceptions are the elementary constituents of matter—such as electrons, quarks, and other fundamental particles.

The standard model is a coherent picture of the fundamental particles and forces of nature, and the work of many physicists operating independently and in groups.

Some physicists suspect that these apparently fundamental particles are emergent as well — though from what exactly, no one can say.
