The 95% CL lower limits on the effective unparticle cut off scaleΛU for a fixed coupling λ = 1. The results from the CMS monojet  and mono-Z  searches, as well as a reinterpretation of LEP and CDF searches  are shown for comparison. The LEP results assume a coupling of unparticles to Z bosons and photons. The CDF (CMS) monojet result is based on a gluonunparticle coupling operator (gluon- and quark-unparticle coupling operators). The inset compares the expected and observed limits for the CMS mono-Z analyses at p √s = 8 and 13TeV. Note that the cutoff scalesΛU for different operators do not have to be identical. Consequently, the comparison shown here with the results other than the CMS 8TeV mono-Z analysis is only qualitative. In the original paper, figure 10 was incorrect. The correct figure is shown above.
