Photon and pi^0 separation by shower shape analysis in the Forward Calorimeter
Summary
Simulations were done to research single photon and pi^0 separation in the Forward Calorime-
ter, which is proposed as an upgrade for ALICE at CERN. Photons from pi^0 decay form back-
ground radiation for direct photon detection. In order to reject the background, the particle
reconstruction needs to identify the particles correctly. Research on the cluster sizes is done
to analyze the clusters left behind by single photons and pi^0 decay photons in the detector. To
do this logarithmic weighting is used. The best value for the logarithmic weighting parameter
w0 was w0 w 5:8.
