   Tel  : 1447                 Room : 3/032
 
   DESY-Group/Experiment : ATLAS

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

   The DESY ATLAS group is doing a measurement of additional particle
   jets in events with top-anti-top quark pairs at the LHC. This
   measurement is important to understand QCD at hard scales and as
   background for Higgs searches and searches for new
   physics. Theoretical calculations at next-to-leading order exist to
   predict top pair production with one additional jet. We will look
   at these predictions as recently implemented in the POWHEG Monte
   Carlo generator and compare to ones with the inclusive top pair
   production. Since the POWHEG generator can be used with different
   parton shower codes, we will investigate the effect of the
   different parton showers on the jet distributions.
