Abstract: A search for new physics is performed based on multijet events with large missing transverse momentum produced in proton-proton collisions at $\sqrt{s}=$ 13 TeV. The data sample, corresponding to an integrated luminosity of 2.2 fb$^{-1}$, was collected with the CMS detector at Run-2 of the CERN LHC. The data are examined in search regions of jet multiplicity, bottom-quark jet multiplicity, missing transverse momentum, and the scalar sum of jet transverse momenta. The observed numbers of events in all search regions are found to be consistent with the expectations from standard model processes. Exclusion limits are presented for simplified supersymmetric models of gluino pair production. For a scenario in which both gluinos decay to a bottom quark-antiquark pair and to a stable, massless, weakly interacting, lightest neutralino, gluinos with mass below 1600 GeV are excluded. For the corresponding scenarios with a top quark-antiquark pair or with a generic quark-antiquark pair in place of the bottom quark-antiquark pair, the respective limits are 1530 and 1440 GeV. These results significantly extend the limits from LHC Run-1.
