Description

A search for the non-resonant production of a pair of the Standard Model Higgs boson $h$ via gluon-fusion, $gg\rightarrow hh$, is performed. Each Higgs boson decays to either $W^+W^-W^+W^-$, $ZZZZ$ or $ZZW^+W^-$ leading to $4\ell+X$ in the final state. The $\ell$ could be an electron or a muon, and $X$ is missing transverse energy or jets. The b-tagged as jets is vetoed in this analysis. The search uses the data at a centre-of-mass energy of 13 TeV collected by the ATLAS detector between 2015-2018 at the Large Hadron Collider. Cut-based and multivariate analyses are used to exploit the signal.
