Ditau mass reconstruction techniques at the ATLAS experiment — •Michael Hübner, Philip Bechtle, Klaus Desch, Christian Grefe, Peter Wagner, and Maike Hansen — Universität Bonn

Ditau mass reconstruction techniques play an important role in analyses involving the Higgs boson decaying to two tau leptons and are used to suppress background from Z→ττ processes. In particular, the Missing Mass Calculator (MMC) was used in the paper providing evidence for the Yukawa coupling of the Higgs boson to tau leptons.

I will introduce the Missing Mass Calculator and show first results of MMC using the new tau substructure reconstruction. Additionally, I will show a performance comparison between different ditau mass reconstruction techniques.
