A general description of modern science is that we have heavily observed and proved to what seems to be the highest level of precision possible, short of observing black holes to the maximum degree, that there are 4 major dynamics which are unrelated to each other beyond their effects on particles.
1: Gravity and space-time affects particles with mass and/or operate in space-time through fields.
2: Electromagnetism affects particles with positive or negative charges through fields and photons.
Can someone tell me which particles are affected by the other 2, their fields, particles etc.. If a particle is unobservable, like a graviton, I would prefer it if you described the process in terms of a field, which is observable.
3: Strong nuclear force
4: Weak nuclear force

Strong nuclear force is carried by gluons and binds together quarks within hadrons.
Weak nuclear force is carried by the W and Z bosons and is responsible for certain types of nuclear radioactive decay. It affects left-handed leptons and quarks.

Are these particles observed? If not, which observed phenomena are these particles based on? If so, what are their properties?
Except the graviton, all of these particles have been observed (photon, gluon, W & Z bosons). However, they are not observed in the classic sense. Instead, we observe particle interactions that should produce them, followed by their decay/exchange products. These observations are usually performed in bubble chambers.

I thought we had agreed that the "force of gravity" was caused by space-time deformation and not gravitons.
Although gravitons would have been cool.

That's just a nice way to describe it. Problem is, general relativity doesn't go well together with quantum mechanics; things break if you try to put them together into one theory. So instead, you need a new theory of gravity that works with QM. It is likely and works best if this theory is also quantized, thus you need a model based on gravitons. We don't have a graviton theory yet that works even remotely as well as GR, but physicists pretty much seem to agree that there is such a thing as gravitons, at a deep enough level.

Uhh lol? Try particle accelerators, i.e. Fermilab and CERN. You sure as shit won't see gluons or W/Z bosons in bubble chambers, not even close.

Most perfect description of gravitons I've seen. You win an internet.

Okay this is pissing me off. How the fuck do you quote things so that it highlights them when you move the mouse over?
