Newest developments and validation of the τ-embedding method for the estimation of genuine ττ backgrounds for H→ττ analyses of CMS — •Sebastian Kaiser, Christian Winter, Roger Wolf, Günter Quast, and Markus Klute — Institute of Experimental Particle Physics (ETP), Karlsruhe Institute of Technology (KIT)

The τ-embedding method, used to estimates all backgrounds with genuine τ lepton pairs in an event, is one of the main pillars for a number of precision measurements in the H→ττ decay channel, of CMS. For this method events with two muons are selected, in data. All energy deposits associated to these muons during reconstruction, are removed from the event record and replaced by the energy deposits of simulated τ lepton decays with the same kinematic properties. The presentation will summarize the method itself and report on the steps undertaken to validate it for the upcoming LHC Run-3 analyses.
