But I refer to particles around ours that it can affect us pshychophysically and we don´t know about it.
Any particle that couples strongly enough to ordinary matter to affect our brains or bodies would have been discovered already: it would be produced frequently by existing particle accelerators.

There are no such unknown particles that could affect us (!!!!) but we wouldn't be able to detect them....
Even if they could affect your psychology or body, they would have to couple/interact very weak (otherwise the detectors would have seen them)... So in fact they couldn't even affect your brain or body as much as cosmic rays can...

@PERFESSER particles in elementary physics are just a set of quantum numbers, and we build theories describing how these quantum numbers work (charge, spin, isospin etc etc......). A theory would be nice if it could quantize the masses (of course they appear in discrete numbers for each particles, but it would be nice to find out how this is done). That's what I'll end up thinking after all these quotations on "E=mc^2 so mass=energy so particles=energy" .
They don't "exist" (in the way that we'd see them)... we see their interactions and that's how we can distinguish between them.
