Re-analysis of the LHC Run-2 data taken with the CMS Experiment in view of a combined LHC Run-2 + Run-3 measurement of Higgs boson STXS measurements in the H → τ τ decay channel — •Tamara App, Artur Monsch, Markus Klute, Günter Quast, and Roger Wolf — KIT, Karlsruhe, Germany

A re-analysis of LHC Run-2 data of the year 2018, after a complete re-reconstruction performed by the CMS Collaboration, in view of an anticipated combined Run-2 + Run-3 measurement of Higgs boson STXS measurements in the H → τ τ decay channel is presented. The level of data understanding is demonstrated indicating the transition towards high precision measurements and the perspective of a future measurement based on a systematic uncertainty aware neural network training is given.
