abstract = {A search is presented for new particles produced at the LHC
in proton-proton collisions at $\sqrt{s}=$ 13 TeV, using
events with energetic jets and large missing transverse
momentum. The analysis is based on a data sample
corresponding to an integrated luminosity of 101 fb$^{-1}$,
collected in 2017-2018 with the CMS detector. Machine
learning techniques are used to define separate categories
for events with narrow jets from initial-state radiation and
events with large-radius jets consistent with a hadronic
decay of a W or Z boson. A statistical combination is made
with an earlier search based on a data sample of 36
fb$^{-1}$, collected in 2016. No significant excess of
events is observed with respect to the standard model
background expectation determined from control samples in
data. The results are interpreted in terms of limits on the
branching fraction of an invisible decay of the Higgs boson,
as well as constraints on simplified models of dark matter,
on first-generation scalar leptoquarks decaying to quarks
and neutrinos, and on models with large extra dimensions.
Several of the new limits, specifically for spin-1 dark
matter mediators, pseudoscalar mediators, colored mediators,
and leptoquarks, are the most restrictive to date.},
