Abstract: The Higgs boson was discovered by the LHC experiments in 2012. Several Beyond the Standard Model theories predict this particle to be a portal to new physics interactions and recent measurements hint at the branching fraction to undetected particles could be as high as 16%. It is thus important to directly search for possible rare and exotic decay modes of the Higgs boson. In this talk, we will discuss exotic Higgs boson decays in the context of a two-Higgs doublet model extended with a complex scalar singlet (2HDM+S) using data from the CMS experiment at LHC's Run-2. The findings in the H→ aa → ττbb final state analysis will be presented. We will also discuss how the CMS experiment trigger system can be utilized to find rare Higgs boson signatures, including new strategies being implemented for LHC Run-3.
