1:00 PM → 1:05 PM Cool Copper Collider - Beam Background Studies

Speakers: Elias Mettner (UW-Madison), Abdollah Mohammadi (UW-Madison)

• Investigating the possibility of overlaps in the detector causing a bug that leads to our "Hits at 0"
  • Lindsey has been speaking with people more familiar with Geant
• Went through the geant setup and run process again to help with Abdollah/Brian
  • Also looked for possible errors or bugs in the log, but didn't see anything that raised alarm
• There may exist a set of code somewhere that directly checks for overlap in the geometry
  • Need to find it first/follow up

1:05 PM → 1:15 PM CCC Initial studies

Speaker: Mr Bryan Nee (UW-Madison)

1:15 PM → 1:20 PM CCC - H > aa > b,b tau,tau

Speaker: Ashling Quinn (U.Wisconsin)

1:20 PM → 1:30 PM Muon Collider - DiHiggs - Delphes Studies

Speaker: Kenny Jia (UW-Madison)

2 approach to solve the memory-over-use issue:

1. minimize the memory use for each module in Delphes:
   1. example of Delphes structure for 2 module 2 events: Module1Init->Module2Init->event1Module1Process->event1Module2Process->event2Module1Process->event2Module2Process->Module1Finish->Module2Finish.
   2. cleaning iterator ealier in Process instead of Finish
   3. running with 10^7 BIB now, takes at least one hour for 100 events
2. reduce the number of BIB particles:
   1. analyze BIB effect after Shivani's mitigation strategy

1:30 PM → 1:45 PM Muon Collider - DiHiggs - Detailed Simulation

Speakers: Ms Shivani Lomte (UW-Madison Physics Department), Carl Vuosalo (UW-Madison)

1:45 PM → 1:55 PM Muon Collider - BSM Physics, DM etc - Delphes Studies

Speakers: Deborah Pinna (Boston University), Varun Sharma (University of Wisconsin - Madison)

1:55 PM → 2:00 PM Next steps

Speaker: Sridhara Dasu (University of Wisconsin)
