Unparticle Physics
read the original abstract
I discuss some simple aspects of the low-energy physics of a nontrivial scale invariant sector of an effective field theory -- physics that cannot be described in terms of particles. I argue that it is important to take seriously the possibility that the unparticle stuff described by such a theory might actually exist in our world. I suggest a scenario in which some details of the production of unparticle stuff can be calculated. I find that in the appropriate low energy limit, unparticle stuff with scale dimension $d_{\mathcal{U}}$ looks like a non-integral number $d_{\mathcal{U}}$ of invisible particles. Thus dramatic evidence for a nontrivial scale invariant sector could show up experimentally in missing energy distributions.

Universal Description of Decoherence in Scale-Invariant Environments
Decoherence in scale-invariant environments is uniquely equivalent to an unparticle bath characterized by scaling dimension d_U, which fixes all exponents via consistency relations and predicts a coherence-protection ...

Probing Neutrino Compositeness with Invisible and Displaced Signals
Neutrinos disintegrate into dark jets in a composite sterile sector, producing enhanced neutral-to-charged current ratios and displaced vertices that probe compositeness scales at facilities like DUNE and FCC-ee.

Kinematic Flow for Banana Loops and Unparticles
Banana loop cosmological correlators are captured by master integrals from tubings of marked graphs, with connection matrices derived from activation, merger, swap, and copy rules unique to unparticle exchanges.
