Optimization of the Search for New Physics in boosted HHb b τ+τ Decays in ATLAS — •Merle Schröder, David Kirchmeier, Wolfgang Mader, and Arno Straessner — IKTP, Dresden, Germany

In searches for physics beyond the Standard Model the resonant production of two Higgs bosons plays an important role. The decay into the b b τ+τ final state is especially promising. While on the one hand, the decay of the Higgs boson into two b quarks has a high branching ratio, on the other hand, the signal from the decay into two τ leptons can be well distinguished from the multi-jet background whilst maintaining a large enough branching ratio. However, the reconstruction of highly boosted di-tau final states from decays of high-mass resonaces above 1 TeV is challenging. Therefore, dedicated algorithms for reconstruction and identification have been developed in the past. The optimization of the analysis and the resulting improvements using the full Run-2 dataset of 139 fb−1 will be shown in this talk.
