Meeting minutes:

1, ECCE integrated detector simulation production summary by Cameron (LANL)

Detailed summary of the simulation production samples and how to access. Welcome inputs on the tracking performance  evaluation.

There is the next ECCE simulation workshop schedule on July 8, see indico page below:

https://indico.bnl.gov/event/12245/

2, Heavy flavor physics study updates and recent tracking performance studies by Xuan (LANL)

Xuan reported the updated HF studies based on the tracking performance for a integrated silicon vertex/tracking system (including estimated service parts) (see details in https://indico.bnl.gov/event/11659/contributions/50175/attachments/34926/56788/LANL_FST_06042021.pdf). Additional topologic cuts suggested before has been implemented to enhance the signal/background ratio. The updated tracking performance provides good capability for HF reconstruction and precise hadron ReA measurements.

Initial results of the tracking momentum resolutions in pseudorapidity bins (0, 1), (1, 2), (2, 3.5) have been presented using both single pion and SIDIS high Q2 events. Need to cross check the stat. uncertainty extrapolation and distributions in the more forward region.

3, Barrel middle-layer material budget by Rey (LBNL)

Rey presented the updated Barrel middle-layer in the All-Si tracker design. Switch to lower material budget mid-layer improves the tracking momentum resolution to meet the EIC YR pwg requirements. Different placements of the barrel middle layers have been studied as well. Studies on the azimuthal and polar angle resolution projected the primary vertex are also presented.

Potential impacts by the service parts are discussed as well.

4, ECCE gas tracker simulation studies by Sourav (Vanderbilt Univ.)

Sorry, I miss the discussion as I joined another local meeting. Please add information here.

5, Tracking performance study by Sebastian (ISU)

Sebastian presented the tracking performance including kinematic coverage for truth, reco tracks and tracking efficiency using the SIDIS high Q2 events. Will study the impacts on the PID.

We also discussed about implementing different detector options and evaluate the corresponding performance. Volunteers to work on this are very welcome.

There are minutes attached to this event. Show them.
