Search for new physics in events with jets, b-tagged jets, and large missing transverse momentum in the all-hadronic channel at $\sqrt{\text{s}}=$ 13 TeV

A search for new physics in events with jets, b-tagged jets, missing transverse momentum, and no leptons, corresponding to an integrated luminosity of 35.9 fb$^{-1}$ collected by the CMS experiment at $\sqrt{s} =$ 13 TeV, is presented. No significant excess of events on top of the standard model background expectation is observed. Results are interpreted in terms of a number of simplified supersymmetry models featuring squark and gluino production, and in terms of the pMSSM-19. For simplified models, lower limits on the gluino (squark) mass are established in the range 1.80-1.95 TeV (1.00-1.05 TeV), assuming a massless lightest supersymmetric particle.
