Request for a DESY Summer Student in 2011
---------------------------------------------------------------

Name : Nick Styles email :nicholas.styles@desy.de
Tel :3103 Room :03/033

DESY-Group/Experiment :ATLAS


----------------------------------------------------------------

Short description of the project the student should work on :

Tau performance studies related to fake rates from QCD jets: Many
ATLAS physics analyses include hadronically decaying Tau Leptons in
their decay chain, which can be identified via several
methods. However, 'fake' tau candidates can occur if a QCD jet is
misidentified as a tau. Due to the very large QCD cross-section at the
LHC, it is crucial to be able to quantify this contribution. The
student will work on data-driven methods to extract these fake rates.

------------------------------------------------------------------

Physics / Computing/ Engineering Content of the project :

Studying the performance of Tau identification algorithms, QCD jets,
at the ATLAS experiment 
Data/Monte Carlo comparisons 
Working mostly within a ROOT-based software framework



------------------------------------------------------------------

Special Qualifications expected from the student ( Computing,...) :

Some programming experience useful, some basic particle physics,
Understanding of the basic principles of physics at hadron colliders


------------------------------------------------------------------
Other remarks :
