Description

HH->bbtautau lies in the sweetspot for the study of di-Higgs owing to its relatively low background and significant branching ratio, making it the most sensitive channel according to the ATLAS Run2 results for the study of Higgs self-coupling. Using Run2+Run3 data collected by the ATLAS Experiment, a significant improvement is expected in the sensitivity to the signal strength. This is an overview of the current status and plans, with particular focus on my work on the study of top and Z-boson background modelling and associated uncertainties.
