I am a Ph.D student at Niels Bohr Institute in Copenhagen.
At the moment I am involved in the commissioning and optimizing of the Tau
trigger at the ATLAS experiment at CERN. My work is focused on the
performance of the Tau trigger in the environment with multiple collisions
per bunch crossing, so-called pile-up collisions. The study is done on the
Monte Carlo samples produced with the Athena software framework.
For my analysis I am using ROOT
and its toolkit for multi-variate analysis in particular. The goal of my
study is to find an ideal set of observables which can be used to select
events with hadronically decaying tau leptons with the top performance in
terms of signal efficiency and background rejection.
