Searches for new phenomena with the ATLAS detector

Many theories beyond the Standard Model (BSM) predict new phenomena accessible by the LHC which prevent for example the need of fine-tuning of the Higgs Boson mass, expand the gauge sectors of the SM or explore the dark sector through possible long lived particle decays. Searches for new physics models are performed using the ATLAS experiment at the LHC focusing on exotic signatures that can be realized in serval BSM theories. The results reported do not touch on Dark Matter signatures and use the pp collision data sample collected in Run 2 by the ATLAS detector at the LHC with a centre-of-mass energy of 13 TeV.
