Search for New Physics with Monojet plus missing transverse energy at CMS

Results are presented for the search for new physics in the monojet plus missing transverse energy channel using pp collision data at a centre-of-mass energy of 7 TeV. The data were collected by the CMS detector at the LHC, and correspond to an integrated luminosity of 36 pb-1. The number of observed events is found to be in good agreement with Standard Model predictions and limits are placed on parameters in the framework of the ADD model and unparticles.
