Search for new physics with monotop final states in pp collisions at sqrt(s) = 8 TeV

We perform a search for new physics in monotop final states, which contain a single top quark and large missing transverse energy induced by a weakly interacting massive particle. The measurement is performed using 19.7~fb$^{-1}$ of $\sqrt{s}=8$ TeV pp collision data, collected by the CMS detector at the LHC. No evidence of new physics is observed and exclusion limits on the mass of dark matter candidates are calculated at 95\% Confidence Level. Scalar and vectorial dark matter particles with masses below 327 GeV and 655 GeV respectively, are excluded.
