Abstract
Description
We show that when the unparticle sector is coupled to the Standard Model, unparticle excitations can decay to Standard Model particles. This radically modifies the signals of unparticle production. We present a method for the calculation of the decay lifetimes of unparticles. In a particular model, we show that depending on their lifetime, unparticles can manifest themselves through monojets, delayed events or prompt decays.
