Reconstruction of DC1 $J/\psi \to e^+ e^-$ decays and use for the low energy calibration of the ATLAS electromagnetic calorimeter
The reconstruction of J/psi decays to e+e- pairs is investigated with DC1 data. The low energy electrons produced are reconstructed by a dedicated algorithm. A rejection of pion tracks of \sim 450 is obtained for an electron identification efficiency of 90%. The background to the J/psi events is est...
