**************************************************** The following has been updated 2013/1/17 **************************************************** ************************** General: ************************** - From KP (and DW): Need PID corrections for all resonances. -> apply to AsymResults.xls to get the corrected reosnance asymmetries -> Table 15 and 16. - From DW: Will help a lot if can summarize all PID corrections, run-by-run values, for all DIS and RES kinematics. ************************** For NIM: ************************** From XZ: Need to add a table summarizing all kinematics including RES. From DW: Need all run-by-run deadtime corrections for RES (values are in the 2013/1/10 writeup, but missing uncertainties). Make sure to include both narrow and wide. ************************** For the resonance paper ************************** From XZ: Need to complete SOM and update the analysis results of the paper throughout. From XZ: Need to contact J. Erler for C1,2 values at RES kinematics (?). Numbers in the resonance paper but not SOM: DIS formula values for Ares. ************************** For the SOM ************************** ---------------------- in Section 3.5, KP/som_bpmcalib.tex ---------------------- From KP: Need bull's eye calibration ---------------------- in Section 3.6, KP/som_optics.tex ---------------------- From KP: need vertex calibration plot for Left DIS#1(Fig.11); -> Then update Table 7. From KP: For RES#7 and #7b, need to check if there was any solid target data (carbon hole, BeO, Al dummy etc), to improve the optics uncertainty. - update near X'mas, we do not seem to have taken any solid target data here. Fine, just keep the large uncertainty then. ---------------------- in Section 3.8, XZ/som_allbg.tex ---------------------- From KP: need corrected contamination analysis for electrons in pion triggers -> Both NIM and SOM Table 9; Update 2013/Jan: DIS is done but need these for resonances, see below. From XZ: The above item will affect the pion asymmetry results, which further affects the positron background analysis and corrections to the electron asymmetry. (Note to self: this is done in my spreadsheet AsymResults.xls). From KP: Also need all contamination analysis for RES -> Table 10; XZ/DW: double check AT on the right HRS was done at Q2=1.907 (Table 14); RM/XZ: Need to use duality for the Al endcap evaluation, so the point that our measured RES asymmetries agree with DIS formula within their stat uncertainties must be made somewhere prior. ---------------------- in Section 3.9, DW/som_radcor.tex ---------------------- From DW: What is the form factor used in the e-p and e-n elastic (part of the quasi-elastic) asymmetry evaluation (line 847-851)? - These are from the HAPPEX code, need to check references! From XZ: need reference for NMC fit of $F_2$ (near line 856). From DW: Need radiative corrections for resonances -> Table 16. Update 2013/Jan: preliminary numbers are available but need fine interpolation to extract A(,) from theory tables. Table 15: Applied all preliminary corrections here (note: RC needs to be updated, see above). Need to re-evaluate error of fRC in Table 16 (DIS should shrink). RC for resonances: How to evaluate error? Note that if table is good to 20%, it would cancel in the RC ratio since A(,) is now from table not DIS. -------------------------------------------------------- Resonance questions: ----------------------------------------------------- Now RES#3 is 3 sigma away! 1) check if A(,) from the table is consistent with the values theorists just sent us. Answer: from asym.ps from Lee (see log 2013/1/10), the value of A at W=1.263 is about -94ppm, agree with DW's number. 2) The large value of RC for RES3 is not only due to being close to QE, but also the APV structure near Delta: If APV is peaked at 1.232 and drops off when it's away from 1.232, then it would appear as if fRC is large, since our average is right on the peak.
