   DESY-Group/Experiment :  ATLAS


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

   Short description of the project the student should work on  :

The LHC has started the operation of proton-proton collision at a
center-of-mass energy of 7 TeV in 2010 and is planning to continue the
operation through out 2011 and 2012. This provides a unique
opportunity to study particle physics phenomena at the highest energy
which allows various searches for new physics as well as precise
measurements of standard model processes.  The production of W boson
associated with jets is a main source of background to many channels
for searching new physics such as the search for Higgs boson or
supersymmetry. Moreover, the production mechanism of W+jets events
varies a lot when there is a jet coming from heavy quarks (c or b
quark).  The student will work on experimental methods to reconstruct
heavy quark jets using ATLAS data in order to measure the cross
section of W+jets production and also investigate how they contribute
as backgrounds to other channels.

   Physics / Computing/ Engineering  Content of the project :

   70 % / 30 % / 0 %


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

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

The work requires a basic understanding of particle physics
phenomenology and writing analysis programs in C++. Experiences with
programming languages and the analysis framework ROOT would be
appreciated but he/she can also learn it during the summer student
program.
