Efficiency measurement of hadronic ττ triggers and their application in the SM H→ττ analysis of CMS — •Maximilian Burkart, Artur Gottmann, Günter Quast, and Roger Wolf — Karlsruher Institut für Technologie, Karlsruhe, Deutschland

The most promising decay channel to measure the coupling of the Higgs boson to fermions is the decay into two tau leptons where the vector-boson-fusion (VBF) production mechanism constitutes a high share of the analysis’ sensitivity. To increase the available amount of signal events a dedicated trigger targeting specifically the VBF production channel of the Higgs boson in the decay into two subsequently hadronically decaying tau leptons has recently been developed by the CMS Collaboration.

This talk covers the efficiency measurement of triggers for hadronically decaying tau leptons using the tag-and-probe method in Z→τ_µτ_h events. The main focus of the talk lies on the application of the measured trigger efficiencies in the SM H→ττ analysis and the sensitivity gains from the usage of the VBF trigger especially.
