Preparation of Higgs boson STXS measurements in the H→ττ decay, based on LHC Run-3 data taken with the CMS Experiment — •Sofia Giappichini, Roger Wolf, Markus Klute, and Günter Quast — Karlsruher Institut für Technologie, Institut für Experimentelle Teilchenphysik, Karlsruhe, Deutschland

This analysis presents measurements of Higgs boson production in the ττ decay channel. The study uses proton-proton collision events collected by the CMS experiment at the CERN LHC between 2022 and 2025, at a center-of-mass energy of 13.6 TeV, with a total integrated luminosity of 287 fb⁻¹. Focusing on both gluon fusion and vector boson fusion production modes, measurements of the signal strengths and cross-sections times branching fraction within the simplified template cross-section scheme are presented. These results provide precise sensitivity to Higgs boson production at high transverse momentum and to event topologies featuring jets.
