  A search for long-lived particles decaying in the outer regions of the CMS
silicon tracker or in the calorimeters is presented. The search is based on a
data sample of proton-proton collisions at $\sqrt{s}$ = 13 TeV recorded with
the CMS detector at the LHC in 2016-2018, corresponding to an integrated
luminosity of 138 fb$^{-1}$. A novel technique, using trackless and out-of-time
jet information combined in a deep neural network discriminator, is employed to
identify decays of long-lived particles. The results are interpreted in a
simplified model of chargino-neutralino production, where the neutralino is the
next-to-lightest supersymmetric particle, is long-lived, and decays to a
gravitino and either a Higgs or Z boson. This search is most sensitive to
neutralino proper decay lengths of approximately 0.5 m, for which masses up to
1.18 TeV are excluded at 95% confidence level. The current search is the best
result to date in the mass range from the kinematic limit imposed by the Higgs
mass up to 1.8 TeV.
