Analysis for Run3 in the HHH → bbbbττ channel with the CMS Experiment — •Thanh Tan Nguyen, Philip Keicher, Marcel Rieger, Nathan Prouvost, Ana Andrade, Bogdan Widerspan, Tobias Kramer, and Peter Schleper — University Hamburg, Hamburg, Germany

Understanding the Higgs mechanism is currently one of the largest fields of research at the LHC. One factor in this endeavor is the measurement of the Higgs self-coupling, which defines the shape of its potential. The sensitivity to this parameter of the standard model increases with the multiplicity of Higgs bosons. This analysis focuses on the triple Higgs production at LHC, which is sensitive to both the triple and quartic self-coupling. Here, the final state of four bottom quarks and two tau leptons is chosen; it*s a compromise between high branching ratio and clearer distinction of the decay products. The current status of this analysis is presented in this talk, with a particular focus on studies on the analysis phase space definition and the derivation of discriminating observables
