The discovery of the Higgs boson in 2012 confirms thevelectroweak symmetry breaking mechanism and validates the Standard Model (SM). All hitherto measured properties of this newly discovered particle are consistent with the SM. While measuring these properties remains one of the main goals of general-purpose high energy physics experiments such as ATLAS and CMS, the Higgs boson discovery can be used as a portal for New Physics to explore and potentially address the known shortcomings of the SM (the hierarchy problem, dark matter etc.). Of these, theories proposing an extended Higgs sector consisting of additional scalar particles are popular due to their being the simplest possible modification of the current scenario. This seminar aims to review the search for two additional scalar resonances proposed by various theories, such as the Two Real Singlet Model (TRSM), the Two Higgs Doublet Model (2HDM), and the Next-to-Minimal Supersymmetric SM (NMSSM). This search is performed to be model independent and uses the Run 2 data collected by the ATLAS detector.
