### Description

I present the most general bounds we can make on operators in hidden CFTs, which are weakly coupled to the SM via a heavy mediator. The conformal symmetry dictates an unusual phase space for the generated particles, which led H. Georgi to coin the term 'Unparticles'. Using the unparticle formalism, we constrain a large class of hidden valley theories without the need to specify their particle and symmetry content.

Our novel result is a consistent theory of unparticle final states in a generic CFT, where previous searches specialised to specific unparticle operators, and its application to current experimental runs. The phenomenology includes collider searches (LHC 2) and low-$E$ experiments.
