Precision studies of the properties of the Higgs and gauge bosons may provide a unique window for the discovery of new physics at the LHC. New phenomena can in particular be revealed in the search for lepton-flavor-violating or exotic decays of the Higgs bosons, as well as in their possible couplings to hidden-sector states that do not interact under Standard Model gauge transformations.

Searches for axion-like-particles (ALPs) in Higgs boson decays, as well as searches for ALP production with two top quarks are presented, using LHC collision data at 13 TeV collected by the ATLAS experiment in Run 2. The searches cover a mass range of ALPs below the Z-boson mass. Novel reconstruction and identification techniques used in these searches are described.
We present searches for rare and beyond-the-standard-model decays of the Higgs boson with the CMS detector using the full run 2 dataset. Amongst others, Higgs boson decays to two (pseudo-) scalars and to invisible particles are discussed.
We present searches for a resonance production in the diphoton final state with a mass lower than 125 GeV, predicted by several theoretical models beyond the standard one, as for example axion-like particles. Different possible production modes at the LHC are investigated.
