DarkSHINE Tracker: Hardware, Reconstruction, Simulation and Analysis¶

1 Tracker R&D¶

Hardware, Operation and Maintenance in Tracker Lab

Speakers: Dian YU (Tsung-Dao Lee Institute), Kang Liu, Lin Yang (TDLI), xiang li (tdli)

2 Track Reconstruction¶

DarkSHINE, ITk Test Beam Data Analysis

Speakers: Dian YU (Tsung-Dao Lee Institute), Kang Liu, Lin Yang (TDLI)

Lin: ITk Test Beam Analysis

October 2024 campaign, SS_20USBMS0000381 module

[fixed issues]

1. make the Corryvreckan framework in the cleanup_EventLoaderMuPixTelescope branch ready for campaign analysis after September 2024;
   • pay attention to shift_triggers parameter when loading telescope data in configuration file -- campaign-dependent;
2. initial orientation of the TelePix plane matters!
   • especially the 3rd Euler angle along Z direction -- campaign-dependent;
   • it is compulsory by Corryvreckan framework to ensure positive correlation in each and every telescope plane before the real alignment
     • -- if not, wrong software set-up.
3. improvement:
   • enable aligning orientations during DUT alignment;
   • alignment of all telescope planes at once;
   • correct noise occupancy set-up.

[results]

1. data at stream 21 ASIC(8,9), ASIC(2,3,4);

2. data at stream 20 ASIC(1,2), AISC(4,5).

3 Simulation and Analysis¶

Speakers: Dian YU (Tsung-Dao Lee Institute), Yufeng Wang (TDLI)

ATLAS: Analysis, Performance and Physics¶

4 ttW/ttH -> Multi-Leptons Analysis¶

Run2, Run3

Speakers: Jialin Li, Lin Yang (TDLI)

HIGP meeting:

The analysis team is proposing a very small change in the charge mis-ID treatment they would like to adopt before unblinding. 

No impact on the results is expected. 

This week we will have an update with a proposed change from ttH(ML) for the 2LSS charge misID estimation, relevant to their unblinding request
