Abstract
A search with minimal model dependence for physics beyond the Standard Model
in events featuring three or four leptons ($3\ell$ and $4\ell$, $\ell = e,\mu$)
is presented. The analysis aims to be sensitive to a wide range of potential
new-physics theories simultaneously. This analysis uses data from $pp$
collisions delivered by the Large Hadron Collider at a centre-of-mass energy of
$\sqrt{s} = 13$ TeV and recorded with the ATLAS detector, corresponding to the
full Run 2 dataset of 139 fb$^{-1}$. The $3\ell$ and $4\ell$ phase space is
divided into 22 event categories according to the number of leptons in the
event, the missing transverse momentum, the invariant mass of the leptons, and
the presence of leptons originating from a $Z$-boson candidate. These event
categories are analysed independently for the presence of deviations from the
Standard Model. No statistically significant deviations from the Standard Model
predictions are observed. Upper limits for all signal regions are reported in
terms of the visible cross-section.
