Invariant Mass Distribution

The two-photon invariant mass distribution can be roughly broken up into four pieces, seen below*.

1) GEOMETRY

Muon, Photon, and Pi- Preshower Plots

These plots were made from 5000 events of each particle type.  For muons, tower clustering was done by setting a seed tower threshold of .25 GeV and a cluster threshold of .33 GeV: for gamma a

First Clustering Plots

The plots show that the clustering works.

BEMC 2008 slopes

Here some plots of slopes for 2008 using runs 9061080, 9062099, 9063032, 9063117, and 9064017, which are all EmcCheck runs. The slopes are attached in a text file.

Polarization

I am using the final polarization numbers from run 6, released by A. Bazilevsky to the spin group on December 4, 2007.  The files can be found below.

Further Preshower Plots

Figures 1, 3, and 5 show plots involving geant preshower energy deposition (i.e., with no calorimeter simulation applied): for each tower-only cluster the preshowers in front of it are identified a
