Unparticle physics is currently a very popular research area. (The initial paper above published in Phys. Rev. Lett. is cited more than 100 times in less than a year.) Thus, it would be nice to have an unparticle thread on this forum as well.

For my contribution to this topic, in which I attempt to answer the question "What the hell unparticle really is?", see:

Ha, you jumped into the herd as well. I was tempted to write up a paper on them right after Georgi published b/c I knew a little about them already from recent research in conformal sectors.

Fun topic, if highly implausible. Already people have analyzed systems with dualities and they don't find any unparticle like spectrums at all, so its probably rarefied at some level..

If someone is interested, a discussion on unparticles is present also here:
