A_LL paper status
----------------------------------------------------------------------------------------------------------------------
REMAINING TASKS:
- Systematics from transverse components
- \delta A_{LL} = | \tan\theta_B \tan\theta_Y \cos(\phi_B - \phi_Y) A_{\Sigma} |
- \cos(\phi_B - \phi_Y) typically conservatively estimated to be 1, since \phi_B - \phi_Y is rather difficult to measure
- Need polar angle of polarization vectors; can be obtained from raw TSSAs [ DETAILS ]
- Need to download run 12 and run 11 scaler files from polarimetry scaler boards; I have code to read them out and Stephen has code to produce asymmetries
- Need A_Sigma (errors)... can be obtained from Run 11 pp500; analysis code already written, just need to feed it a clean set of trigger trees (FMS "outputfiles")
- \delta A_{LL} = | \tan\theta_B \tan\theta_Y \cos(\phi_B - \phi_Y) A_{\Sigma} |
- Update run 12 & run 13 trigger trees using Steve's updated clustering / isolation code (from the work he's done over this past summer)
- Run 12 is done! Only needed to reproduce outputfiles (~day of processing time), not their preceding analysis file, the ofiles (~almost week of processing time)
- Reproduce A_LL plots binned in p_T for two different eta ranges
- Eta max range has been changed to 2.65-3.9 to trim off sharp fall-offs in the eta distribution of pi0s
- Carl suggests plotting eta distributions and one should see a large change at a particular eta, likely at the large-small cell boundary
- large-small cell boundary ranges from eta=3.45 at phi=0 to eta=3.105 at eta=pi/4
- [ OVERALL ETA DISTRIBUTION ] [ RUN BY RUN ETA DISTRIBUTIONS ]
- Currently considering eta bins 2.5-3.28 (mostly large cells) and 3.28-4.0 (mostly small cells)
- [ RUN 12 LARGE CELL A_LL ] [ RUN 12 SMALL CELL A_LL ] [ DATA POINTS ]
- Systematic error bars need to be updated (since the current ones are based on the ZDC vs. VPD comparison via bunch-fitting)
- Finish up theory curves [ LINK TO STEPHEN'S PLOTS ]
- Double-check sigma_max equation (Stephen wants to find the "orignal paper" and cite it)
- Any comments / suggestions (e.g. on grammar, content, organization, presentation, etc.)?
