| 520 | _ | _ | |a The Higgs boson is the most recent fundamental particle to be experimentally observed. Due to its large mass and its couplings to massive bosons and fermions, it has a wide variety of decay channels. Among them is the still unobserved rare decay $H \to Z(\ell^+\ell^-)\gamma$. In this thesis, a search for the $Z\gamma$ decay mode of the Standard Model Higgs boson as well as potential new higher-mass resonances decaying to the same final state is presented. The analysis is based on a dataset of 36.1 fb$^{-1}$ of proton-proton collisions collected with the ATLAS detector at the CERN Large Hadron Collider at a centre-of-mass energy of 13 TeV. No significant excess of events over the background-only expectation was observed, and consequently, an upper limit at the 95% CL on the cross section times branching ratio of 6.6 times the Standard Model expectation was derived. The expected upper limits were determined to be 5.2 (4.4) times the Standard Model expectation when assuming the presence (absence) of this decay mode. |
