Since the discovery of the Higgs boson, an enduring goal of the experiments at the Large Hadron Collider (LHC) has been to uncover evidence of a more fundamental theory underpinning the Standard Model (SM) of particle physics. Though the SM has been remarkably successful in predicting experimental data, there are still observations that it is unable to describe or explain. One approach to the
search for evidence of new physics is through Higgs boson pair production, a process that occurs at a very low rate in the Standard Model and which could be enhanced by the presence of unexpected interactions. This talk will focus on
the search for Higgs boson pair production with the ATLAS detector in a final state with two bottom quarks and two tau leptons, spanning recent results in the resonant and non-resonant searches and including techniques developed to search for highly boosted events.
