Track and SecondaryVertex Reconstruction of Tau Leptons in ATLAS — •Kevin Bass, Peter Wagner, Michael Huebner, Klaus Desch, and Philip Bechtle — Universitaet Bonn

The Higgs boson decay into two tau leptons offers a unique way to test the Standard Model. Techniques to better characterize this decay in data collected from LHC runs are being improved. The Missing Mass Calculator (MMC) is used to estimate the di-tau mass and is an important discriminator between signal and background processes. I will introduce the concepts behind tau vertex reconstruction both in regards to and independently of the MMC and show how it can help to improve the predicted Higgs boson mass.
