Description

This talk presents a search for beyond-the-standard-model heavy resonances decaying into Higgs boson pairs in the bbtautau final state, using the full Run 2 dataset collected by the CMS experiment, corresponding to 138 fb^-1 of proton-proton collisions at a center of mass energy of 13 TeV. The analysis targets events where one tau lepton decays hadronically and the other either hadronically or leptonically. In the TeV mass range, the decay products of the Higgs bosons become highly collimated, requiring dedicated reconstruction techniques. The search leverages advanced machine learning algorithms for identifying boosted hadronic tau decays and substructure-based methods for tagging Higgs->bb candidates.
