TbyT analysis of 7p3GeV_fixedTarget_2020 file reconstructed with SL21d and SL23e
Updated on Sat, 2023-12-09 11:15. Originally created by fisyak on 2023-12-09 11:15.
The Track by Track analysis has been done for 7p3GeV_fixedTarget_2020 file reconstructed with SL21d and SL23e.
The chains were different:
SL21d : "DbV20220117,P2020a,StiCA,FXT,BEmcChkStat,picoVtxFXT,PicoCovMtxWrite,-beamline3D,-OPr13,OPr40,evout,-hitfilt"
SL23e : "DbV20231004,P2020a,StiCA,FXT,-mtd,picoVtxFXT,PicoCovMtxWrite,BEmcChkStat,-OSpaceZ2,-OGridLeakFull,evout,-hitfilt"
The results can be found at
https://www.star.bnl.gov/~fisyak/star/TbyT/7p3GeV_fixedTarget_2020_SL21d_SL23e/
The differences are within ~0.1%.
My guess is that the hit distribution difference reported by Yue Xu (https://drupal.star.bnl.gov/STAR/system/files/Acceptanceindffproduc_20231208.pdf) on slides 6-7 is coming from her triton and He3 z-cut.
