General points:

  • Please focus on Run 3 if you can

  • Test test test! (ask summer students to test?)

  • How much space do you need?

  • At least for long exercises: make sure the space is used well, like installing one thing in one place and another thing in another space. No 100 GB AFS space available for participants :)

  • docs.cern.ch (md) instruction pages very useful for the exercises and for documentation for later usage. If interested, you can contact the TOP exercise facilitators Evan and Dominic

 

For the timetable:

  • Consider cut-off for the long exercises with deadline to upload slides, give time to practice slides → important for facilitators to mind giving the students enough time to prepare the talk

 

Inclusive jets (SMP) - Patrick Connor

  • 1 TB EOS account more than enough

  • Short exercise on unfolding is combine-based rather than TUnfold, so yes, please cover TUnfold as part of your long exercise

  • All 3 options for exercise are fine with us. Practically: choose the one that’s easiest to find a co-facilitator

    • No other 2D cross section measurement, so that might be good to choose

    •  

 

Ttbar cross section (TOP) - Evan Ranken and Dominic Stafford

  • Could recruit a 3rd facilitator once we know how many participants for the exercise (would want if > 6 participants)

  • Exercise-specific pre-exercise: not essential if done before, but helpful if done

    • Need to give them the list of participants for this exercise well in advance of DAS starting

  • Uses pepper, runs on nanoAOD

  • Includes combine component (doesn’t matter if not everyone has seen combine in short exercise)

  • Add to pre-exercises: request extensions on space

  • Ask O&C about 2025 DAS directory for big exercise files. Only facilitators have write access?

 

Higgs to 4 leptons (HIG) - Daniel Savoiu, Matteo Bonanomi

  • Setting it up on lxplus

  • Prerequisite: grid certificate

 

Displaced search (EXO) - Jeremi Niedziela

  • First time for this exercise

  • Based on the TEA framework (loops, c++ and python)

  • Runs over LLPnanoAOD

  • Would be useful to use data in ABCD (other long exercises may not use)

    • Would be good also for later documentation for ABCD: use EXO methods forum docs

  • Should have combine limits, central corrections, (more optionally: muons and jets) short exercises as prerequisite

  • Other facilitators? Jeremi will look

  • Good to inject signal into data 🙂

 

Anomaly detection (EXO) - Karim?

 

Dark matter (EXO/NPS) - Danyer Perez Adan

  • Will prepare monojet analysis exercise from 2024, it was well documented

  • Can look for facilitator from DESY, but not a problem if we don’t find one since it’s his own framework. Dominic? Mostly need someone in the room, rather than on the technical side

  • Will use his own framework based on c++

  • AFS for setting up scripts and submitting jobs, storage on EOS

  • Either use samples from 2024 school or use 2016 Open Data on EOS

    • Conclusion from meeting: don’t use Open Data

  • Grid access is prerequisite

  • Dependent on MET. need short exercise on MET or ask Andreas if he can include something on MET in the jet exercise. Or could be part of this long exercise

 

**write down: max of 3 short exercises per participant

 

  • Add a facilitators mattermost channel

 

Next meeting: late august

There are minutes attached to this event. Show them.
