---+!! Search for new physics in monojet events in pp collisions at sqrt(s) = 8 !TeV

---++ Abstract
Results are presented from a search for particle dark matter (DM), extra dimensions, and unparticles using events containing a jet and an imbalance in transverse momentum. The data were collected by the CMS detector in proton-proton collisions at the LHC and correspond to an integrated luminosity of 19.7 fb<sup>-1</sup> at a centre-of-mass energy of 8 !TeV. The number of observed events is found to be consistent with the standard model prediction. Limits are placed on the DM-nucleon scattering cross section as a function of the DM particle mass for spin-dependent and spin-independent interactions. Limits are also placed on the scale parameter M<sub>D</sub> in the ADD model of large extra dimensions, and on the unparticle model parameter &#923;<sub>U</sub>. The constraints on ADD models and unparticles are the most stringent limits in this channel and those on the DM-nucleon scattering cross section are an improvement over previous collider results.
