What are the sub atomic particles whose existence has been verified?

Question

And briefly, what are their characteristics?
And what, please, are the theoretical sub atomic particles whose existence has not been verified. Thank you

Answer 1

As far as I know, here are the known fundamental particles. All of these have been observed experimentally.

6 types of quark:
The up quark, down quark,
charmed quark, strange quark,
bottom quark, and top quark.

3 types of leptons:
The electron, muon, and tau particle

3 types of neutrino:
The electron neutrino, muon neutrino, and tau neutrino.

But wait, there's more ...

For each particle, there is also an associated anti-particle.

Many subatomic particles (such as protons and neutrons) are made up of various combinations of three quarks, or of three anti-quarks.

And there are particles that are made up from a quark plus an anti-quark.

Also, some people might count photons, gravitons, and gluons as particles. Depends on your point of view, perhaps. Not sure what the prevailing thought of the particle physics community is on this.

That's about all I can remember of the known particles. There is also talk of the "Higgs boson", but none have been observed yet.

p.s. Nice avatar there, mrjeffy.

Answer 2

There are so many subatomic particles that it is frequently referred to as the "subatomic zoo".

The Particle Data Group at Berkeley keeps an extensive list with information on masses, charge, parity, and so on:

Answer 3

There many, many, verified subatomic particles.
Of course, there are the obvious particles which everyone has heard of....Proton, Neutron, Electron....but there are also several other categories of other particles as well, each with their own characteristics.
