abstract = {An inclusive search for nonresonant signatures of beyond
the standard model (SM) phenomena in events with three or
more charged leptons, including hadronically decaying $\tau$
leptons, is presented. The analysis is based on a data
sample corresponding to an integrated luminosity of 138
fb$^{-1}$ of proton-proton collisions at $\sqrt{s}$ = 13
TeV, collected by the CMS experiment at the LHC in
2016-2018. Events are categorized based on the lepton and
b-tagged jet multiplicities and various kinematic variables.
Three scenarios of physics beyond the SM are probed, and
signal-specific boosted decision trees are used for
enhancing sensitivity. No significant deviations from the
background expectations are observed. Lower limits are set
at 95\% confidence level on the mass of type-III seesaw
heavy fermions in the range 845-1065 GeV for various decay
branching fraction combinations to SM leptons. Doublet and
singlet vector-like $\tau$ lepton extensions of the SM are
excluded for masses below 1045 GeV and in the mass range
125-150 GeV, respectively. Scalar leptoquarks decaying
exclusively to a top quark and a lepton are excluded below
1.12-1.42 TeV, depending on the lepton flavor. For the
type-III seesaw as well as the vector-like doublet model,
these constraints are the most stringent to date. For the
vector-like singlet model, these are the first constraints
from the LHC experiments. Detailed results are also
presented to facilitate alternative theoretical
interpretations.},
