Abstract

The Higgs boson decay to four leptons, provides good
sensitivity for the measurement of its properties due to its high signal-to-background
ratio (S/B), which is better than two for each of the four final states: $4\mu$,
$2e2\mu$, $2\mu2e$ and $4e$, where the
first lepton pair is defined to be the one with the dilepton invariant mass closest to the $Z$ boson mass.
These proceedings summarise several preliminary results on the properties of the Higgs boson decaying to four leptons final state
using $14.8$~fb$^{-1}$ of integrated luminosity collected in $pp$ collisions by the ATLAS detector at the LHC
at a centre-of-mass energy of 13 TeV. The results include measurements of the fiducial cross sections, the different
production mode cross sections and a test of beyond the Standard Model interactions using
an effective Lagrangian approach.
