Deconstruction of Unparticles

Abstract

We discuss properties of hypothetical scale invariant (unparticle) matter by viewing it as a tower of massive particles. We show how peculiar properties of unparticles emerge in the limit when the mass spacing parameter Delta vanishes. We explain why unparticle cannot decay in this limit and how, for finite Delta, the decays manifest themselves in a relation between the reconstructed invariant mass and vertex displacement. We describe a model field theory in AdS5 which explicitly implements the deconstruction procedure by truncating the extra dimension to size of order 1/Delta.
