''' Research description: '''
 +
 +
The matter in the Universe is dominated by an up to now unknown component called Dark Matter. The nature of this Dark Matter is one of the major open question in modern astro particle physics.
 +
In the last decades a lot of efforts were put into the search for Dark Matter particles, and experiments at the Large Hadron Collider (LHC) form part of this search effort. In ATLAS for example, new particles that could make up Dark Matter are searched for in the mass range of GeV to several TeV. One fascinating possibility of producing Dark Matter and discovering it at the LHC is via the coupling to the Higgs boson, which was itself only discovered in 2012.
 +
The student's task will be to implement an analysis code to reconstruct events where a Z boson and a Higgs boson are produced together. In order to do that he/she will learn how to use the ROOT software package and will then be asked to study simulated ATLAS data. Finally he/she will try to improve the baseline analysis improving the rejection of the background over the signal.
