We present a search for scalar and tensor unparticles in the diphoton final state produced in pp collisions at a center-of-mass energy of 10 TeV, with the CMS detector at LHC. The analysis focuses on the data sample corresponding to the integrated luminosity of 100 pb−1, expected to be collected in the first LHC run. The exclusion limits on unparticle parameters, scaling dimension dU and coupling constant lambda, and the discovery potential for unparticles are presented. This is the first simulation study of the sensitivity to unparticles decaying into the diphoton final state at a hadron collider.
