Improved event cleaning for the τ-embedding method of CMS — •Christian Winter, Sebastian Brommer, 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 an selected-event in data with simulated τ-decays. For this purpose, the muon signatures have to be removed from the original event record. This talk will focus on an improved cleaning, which takes electromagnetic muon showering in the muon detectors into account.
