Meeting Notes for Next Telecon

Agenda for Sep 3, 2025

quarknet.org

• Current page on i2u2-quarknet
• Xeno Media Basecamp page for issues

e-Labs

• e-Labs issues tracking page (Google Doc)
• Edit and Joel are setting up a sandbox VM to test problems with uploads.

Cosmic

• Cosmic Watches have been very popular at workshops. Several teachers have asked about purchasing CWs. Might it be possible to considering making, and selling CWs at cost? This could be a way to continue to promote CWs without taxing the budget and/or the logistics of centrally "checking out" sets of CWs.

CMS

• CIMA issue continues. We are making Google sheets for masterclasses that take place this summer.
  • Plan to resolve before IPPOG at end of October by either placing old CIMA on CERN server or creating new CIMA.
• Ken met Uta last Friday on Zoom to set dates for IMC 2026:
  • W2D2 will be Nov 20, 2025.
  • CERN videocons Feb 18 - Apr 1
  • FNAL videocons Mar 2-28
• More news from meeting with Uta: Uni Bonn is working on a new version of the LHCb masterclass. The old measurement has problems in the first half.
• Expected for IMC 2026: all or almost all CMS data from CMS Run 2. Stay tuned. The new set will include 840 fout-lepton events, almost 4x what we had available in Run 1.

• Masterclass preparation
  • The new masterclass event display files are produced from 2016 MINIAOD. There was a problem with global muon propagation in MINIAOD where they would not show up in the display. This is now fixed and the 4-lepton events have all been regenerated with the fix: https://github.com/QuarkNet-HEP/cms-masterclass-scripts
  • The selection criteria from 2016 have been applied for W events and csv files have been produced. Next to be produced are event displays files. https://github.com/QuarkNet-HEP/Wmunu-jupyter, https://github.com/QuarkNet-HEP/Wenu-jupyter
