ττ background estimation with the τ-embedding method of CMS in Run3 — •Jannik Demand, Christian Winter, Artur Gottmann, Roger Wolf, and Günter Quast — ETP, Karlsruhe Institute of Technology, Karlsruhe, Germany

In H→ ττ analyses a major source of background are genuine tau leptons, mostly originating from Z→ ττ decays. The τ-embedding method is a method to estimate this background from data, by replacing muons in selected events in data with simulated τ-decays. This talk will explain the method and gives a report on its applicability on Run3 data.
