Realistic seeding studies by Rey:
Import the same parameters of the ACTS algorithm in Jugler and EICrecon. Compared the reconstructed seeds between the sPHENIX default and the ePIC configuration. Tuned the finding parameters and studied the effiency as a function of eta with different pT, theta angle and acceptance. Study the multiple seeds and mutiple tracks tuning to filter out the duplicated tracks. Working on the realistic seed to track reconstruction.
Suggest to 1) include the MPGD and AC-LGAD layers/planes for the tracking seeding, 2) to apply two iterations of seeding, starting with central track seeding and then adding the forward/backward region, 3) call different ACTS parameter tuning for the ePIC tracking detector, 4) refer to latest track reconstruction updates in
https://indico.bnl.gov/event/18366/ , 5) develop the flag to compare the truth and realistic seeding, 6) after the single particle tuning is done, to evalute the performance in DIS event and then add the background hits.
Tracking performance with smearing by Shyam:
Smearing the trakcing momentum with different smearing fractions from 0.01 to 0.9. Study the DCA_2D and momentum resolutions in different pseudorapidity regions based on truth seeding.
EIC siliocn consortium report by Ernst:
Present the motivation of the current ePIC MAPS detector configuration. Discussed optimized the geometry to add more points for track reconstruction. Compared the tracking performance with curent detector geometry and “doubling-up” all disks in fast simulation. Due to the additional material budget, the tracking momentum resolution is worse in the “doubling-up” disk configuration than the current ePIC geometry. Suggest to doubling the outmost disk and work inwards or add one additonal disk in the hadron-going (or electron-going) direction. Other options discussions such as increasing the disk radius
