One of my friends suggested I read an article about unparticle stuff written by one of the professors here.
The article itself, while not exactly nonsensical, had no significance to me because I have no idea what the equations mean.
So I thought to myself, let's start at the beginning: what the hell is an unparticle? So far, I gather that an unparticle state is one with negative square norm.
Is there anything more intuitive to an unparticle?
Furthermore, what is unparticle stuff? Does that just mean a system composed of unparticles?
Help?

Your first question I can't answer, I am stuck at that same point. Now don't get me wrong I can't answer anything, don't even think Georgi can with any certainty, but wouldn't unparticle stuff be just as you said, a system of unparticles. Matter that is not particle composed matter, but unparticle composed and being scale invariant.

What makes me scratch my head is the scale invariance of unparticles which would not have zero mass. I understand his comparison with Neutrinos and he actually makes me wonder.
