Search for dark matter in monojet events in proton-proton collisions at $\sqrt{s}$=13 TeV

We will present a search for dark matter in proton-proton collisions at center-of-mass energy of 13 TeV. A search has been performed using events containing a single energetic jet and large missing transverse momentum. The data were collected by the CMS detector at the LHC and correspond to an integrated luminosity of 2.1 fb$^{-1}$. The results of search will be discussed in terms of various dark matter benchmark models.
