Unparticle self-interactions

Understand

We develop techniques for studying the effects of self-interactions in the conformal sector of an unparticle model.

• Their physics is encoded in the higher n-point functions of the conformal theory.
• We study inclusive processes and argue that the inclusive production of unparticle stuff in standard model processes due to the unparticle self-interactions can be decomposed using the conformal partial wave expansion and its generalizations into a sum over contributions from the production of various kinds of unparticle stuff, corresponding to different primary conformal operators.
• Such processes typically involve the production of unparticle stuff associated with operators other than those to which the standard model couples directly.
