Spin asymmetry statistical errors, part 2

Updated on Wed, 2008-08-20 18:32. Originally created by kurnadi on 2008-08-20 18:14.

Updated the dE/dx cut. Previous asymmetry calculations was using +/- 3σ in dE/dx. The following has a tighter cut on the lower end, varies with momentum bins.

ALL by : fill, run

AB by : fill, run

AY by : fill, run

 

 

Latest asymmetry with tighter dE/dx cut and new Vertex-Z and Point-η cuts:

 

A_LL by fill, with new Vertex-Z and Point-Eta cuts

A_B by fill, with new Vertex-Z and Point-Eta cuts

A_Y by fill, with new Vertex-Z and Point-Eta cuts

By run: A_LL, A_B, A_Y

And that's the best reduced χ2 values I can get with partial 2005 pp data.
