Yield Extraction

 After all the pion candidates have been found and all the cuts applied, we need to extract the number of pions in each bin (in each spin state for ALL.)  To do this we simply

Cuts and Parameters

Here I will detail the some general information about my analysis; topics that aren't substantial enough to warrant their own page but need to be documented.

Pt Dependent Mass

The two-photon invariant mass is given (in the lab frame) by

M = Sqrt(2E1E2(1 - Cos(theta)))

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.
