Updated on Tue, 2008-03-11 11:16. Originally created by kocolosk on 2008-03-05 17:32.Here’s a summary of results for null-test calculations of single-spin asymmetries for the Run 5 charged pion A_{LL} analysis. Asymmetries are defined as (Y,B):
Yellow Beam: -1 x { (++ + +-) - (-+ + —) }
Blue Beam: -1 x { (++ + -+) - (+- + —) }
Like-Sign: (++) - (—)
Unlike-Sign: (+-) - (-+)
All the asymmetries incorporate final beam polarizations.
Combinatoric Background
The last piece of the invariant mass distribution is the combinatoric background. This is the result of combining two non-daughter photons into a pion candidate. Since each photon in an
Low Mass Background
The low mass background is the result of single photons being artifically split by the detector (specifically the SMD.) The SMD fails in it's clustering algorithm and one photon is reconstruc

Eta Peak
I treat the eta peak in a similar way as the pion peak. I throw single etas, flat in Pt from 2 - 25, and reconstruct the two-photon invariant mass distribution for the results. The thro
Pion Peak
To study the pion peak section of the invariant mass distribution I looked at single pion simulations. The pions were thrown with pt from 2 - 25 GeV/c flat and were reconstructed using the cu

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
