Abstract: A search for new physics is reported in multijet events with large missing transverse momentum produced in proton--proton collisions at $\sqrt{s}=8$ TeV using a data sample corresponding to 19.5 $\mathrm {fb^{-1}}$ collected with the CMS detector at the Large Hadron Collider. The data sample is divided into threejet multiplicity regions of 3--5, 6--7, and $\ge8$ jets, and studied further in bins of two sensitive variables --- the scalar sum of jet transverse momenta and missing transverse momentum. The observed numbers of events are consistent with the standard model expectations which are determined directly from the collision data. Exclusion limits are presented for several simplified supersymmetric model topologies. The squark masses are excluded up to 0.75 TeV in the case where the squarks decay to a jet and the lightest supersymmetric particle. The gluino masses are excluded up to 1.1 TeV when the gluinos decay to two jets and the lightest supersymmetric particle.
