Momentum resolution for 2016 (HFT), 2017 (-HFT), 2020 (iTPC), 2021 (CF4)
Updated on Fri, 2020-04-03 11:34. Originally created by fisyak on 2020-04-03 11:34.
In order to measure effect of CF4 addition to TPC gas mixture (90% Ar, 7% CH4, 3% CF4) simulation of ~10 k Hijing events AuAu200 with primary vertex σZ = 30 cm and reconstruction was done for four different geometries:
- 2016 : with HFT
- 2017: no HFT
- 2020: iTPC
- 2021: iTPC + CF4
Detailed comparison of the reconstruction results is presented at https://www.star.bnl.gov/~fisyak/star/muMc/CF4/
The momentum resolution σ(pT)/pT = (1/pT_RC - 1/pT_MC)/(1/pT_MC) is presented below:
