The CMS Run2 resonant HH → bbττ analysis — •Tobias Kramer, Marcel Rieger, Peter Schleper, Ana Andrade, Nathan Prouvost, and Bogdan Wiederspan — Hamburg University, Hamburg, Germany

This contribution presents an analysis in the search for the decays of heavy spin 0/2 resonances to a pair of Higgs bosons in the bbττ final state. A wide mass range of the hypothetical resonance from 250 GeV up to 3 TeV is covered. The analysed data correspond to 138 fb⁻¹ recorded by the CMS experiment at the LHC from 2016 to 2018. The talk highlights key aspects, such as the momentum regression of the neutrinos from the tau decays and the neural network for signal-background classification, and will present the results of the analysis.
