On the Decay of Unparticles

Understand

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.
