Unparticle Physics

Hum... looks like this is another theory that could possibly be tested with the LHC (I think they need to start putting out the "Now Serving...." number machine there at CERN).

In scale-invariant theory—where objects don’t change when their dimensional qualities are multiplied by a rescaling parameter—the concept of particles doesn’t work because most particles have a definite nonzero mass. In quantum mechanics, this isn’t a problem because the standard model does not have scale-invariance. But Georgi suggests that there could be an undiscovered sector of the standard model that is exactly scale-invariant.
