Dear Colleagues

We are planning to have a DSC meeting tomorrow at 0900h BNL time to discuss updates. Sorry, for late notice, I was on travel. I know, there are holidays in Czech Republic, so I wanted to ask if Alexandr and Subhadip would like to connect this time. If not, then let me know, so we can talk later. Also, David, what is your situation? Are you ready to discuss your update tomorrow? Please let me know if you are ready for discussion tomorrow.

Dear Colleagues

I wanted to summarize the meeting below:

1. Leszek - presented progress on tile testing effort at OSU.

2. Subhadip did additional check of clustering without requiring exactly 1 truth and 1 reco cluster. There are some discrepanciencies for ~0.4% of cases, probably due to splitting. There will be a combined effort looking at that - Cluster Splitting Task Force. Please follow these activities.

3. David was able to fix all the problems with the reproduction of Daniel-Han's results and now will do tests for backward HCal. The plan is to show first results (when they are ready) at the calorimetry meeting to spark discussion on the topic.

Best regards, Leszek

Dear Colleagues

We are planning to have a DSC meeting on Friday this week at 0900h BNL time - note the time change vs. Europe. Here's the meeting link:

https://osu.zoom.us/j/99011057540?pwd=QmNhTDBrNmMyckdWYnJqcmFLMHl5QT09

The plan is to have a work in progress updates on:

1. Clustering

2. Position resolution study

3. Neutron reconstruction with ML

David, any progress on communication with Daniel or LFHCAL group? Could you please include me in your e-mails?

Next week, there will be a STAR Collaboration meeting, so we will skip the DSC meeting.

Best regards, Leszek

Dear Colleagues

Today we had a very productive meeting. Thanks for the updates! Here are the main points discussed and tasks to do:

It looks like clustering is performing very well - good enough for jet study.

Here are the check for Subhadip and Alexandr

1. Check the performance for all events insted of requiring exactly 1 reco and 1 truth cluster

2. Check logWeightBase impact on clustering performance - adjust it based on the Awes et. al. paper
3. Do position resolution study for: 5cm x 5cm tiles, 15 cm x 15 cm, 25 cm x 25 cm - try to describe the scaling of resolution with tile size using a fit
4. See if adjusting the localDistXY to values greater than 15 cm affects clustering with eg. 20 cm tiles
5. Adjusting logWeightBase may reduce the difference between reco and truth clusters for the outer high material-budget region
6. Check nhits vs. energy for reco and truth clusters
7. Calculate average efficiency and resolution vs. energy to see the scaling - try to describe it with a fit ~1/sqrt(E)

David

1. Contact Daniel and LFHCAL group to understand the difference between their training results

2. Check the ML parameters and send them to us - some may impact the training performance

Best regards, Leszek

Dear Colleagues

We are going to have a DSC meeting on Friday at 0900h. Here's the link:

https://osu.zoom.us/j/99011057540?pwd=QmNhTDBrNmMyckdWYnJqcmFLMHl5QT09

As we discussed last time, we plan to have work in progress updates on the tasks:

1. Clustering optimization. I contacted experts via calorimetry mailing list. Make sure you follow this discussion. There is also a way to pass parameters to eicrecon, without the need to recompile it: https://eicrecon.epic-eic.org/#/table_flags/flags_view , but please make sure they get passed to the algorithm. I have a feeling that some hardcoded values may remain unaffected.

2. Position resolution study - progress.

3. Neutron reconstruction with ML - update.

Best regards, Leszek
