So far, the "quark" is believed to be the most tiny fundamental particle.
The smallest particle in physics is considered to be the quarks and leptons, which are elementary particles that make up matter. These particles are not believed to have any substructure and are considered fundamental building blocks of the universe.
observable ? i'd say quarks.
The term 'particle' broadly encompasses any relatively small piece of matter, but in particle and nuclear physics, quarks and electrons are smallest, followed by protons, then neutrons.
There is none. To study particle physics you use the whole machinery of quantum physics, but written down in a different way. That means particle physicists use the formalism of quantum field theory, which is a more powerful way of doing quantum mechanics, it's just more useful in this context.
The smallest particle in quantum physics is typically considered to be the quanta of energy known as a photon, which is a fundamental particle that carries electromagnetic radiation. However, there are also other elementary particles such as electrons, quarks, and neutrinos that are considered fundamental building blocks of matter.
Particle Physics
The smallest particle of an element is called an atom.
An atom is the smallest particle of a substance.
A quark is the smallest particle in matter.
The smallest particle in the atom is the electron.

G40 is a supernova remnant. Particle physics is the study particles, radiation and matter. One would be able to study the properties of the G40 by applying the principles of particle physics
