   Tel  :  1544/4845                  Room : 3/33, 3/120
 
   DESY-Group/Experiment : ATLAS

 
   ----------------------------------------------------------------
   
   Short description of the project the student should work on  :


Since one year the LHC is delivering pp collisons to the ATLAS
experiment. The expected amount of data in 2011 will significantly
increase. Already up the the summer 2011 the current dataset will be
enlarged and many searches for new physics will become sensitive.

The summer student will contribute to the ongoing search for the
di-photon with large missing transverse energy final state as
predicted in supersymmetry and large extra dimensions. He/she will
study the calorimeter performance and investigate the possibilty to
use the calorimeter cell timing to measure the production time of
photons compared to the nominal interaction time. A deviation from it
is a clear hint for long lived particles, as neutralinos, decaying
into photons.

   Physics / Computing/ Engineering  Content of the project :

The main emphasis of this project is on data analyis with a good
understanding of the ATLAS liquid argon calorimert.


  ------------------------------------------------------------------
 
  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.
