ATLAS PUB note draft status aiming for Seattle workshop

The ATLAS collaboration is progressing with the pub note draft aimed for submission, with effective reviews from Zhijun leading to comprehensive refining of comments. The draft has been circulated among collaborators, and initial action items from Tom LeCompte have been outlined, focusing on necessary statistical adjustments and limits. Preparing for the Snow Mass workshop, we are moving towards utilizing the Snow Mass Energy Frontier parametrized Fast Simulation framework, with practical instructions available. Discussions are ongoing about the relevance of studying EF hadron collider facilities and the limits-setting framework for future analysis.

Presentation Transcript

  1. ATLAS PUB note draft status aiming for Seattle workshop • Nice and efficient interactions with our note reviewer Zhijun last Friday, all reviewer’s comments are addressed • Pub note draft circulated to ATLAS collaboration last Saturday with Bill’s help: • https://cds.cern.ch/record/1554610 • First action items come up based on the comments by Tom LeCompte: • 1) y-axis’ range of the signal significance plots should stops at 7-σ • 2) need to provide 1.96-σ values to reflect 95% CL limits • …

  2. Plan for Snow Mass • Moving on to use Snow Mass Energy Frontier parametrizedFastSimulationframework. Very practical instructions shown here: • http://www.snowmass2013.org/tiki-index.php?page=Energy_Frontier_FastSimulation • EF Hadron collider facility list: (do we need to study them all?) • http://snowmass2013.org/tiki-index.php?page=EF+Facilities+List • LHC 14 TeV, 300/fb , spacing: 25 ns, pileup: 50 events/crossing • LHC 14 TeV, 3000/fb (HL-LHC) , spacing: 25 ns, pileup: 140 events/crossing • LHC 33 TeV, 3000/fb (HE-LHC) , spacing: 50 ns, pileup: 225 events/crossing (missing…) • VHE-LHC 100 TeV, 3000/fb, spacing: 50 ns, pileup: 263 events/crossing (missing…) • VLHC at 100 TeV, 1000/fb , spacing: 19 ns, pileup: 40 events/crossing • Limit setting framework: • stick with the current p-Value based N-σ discoveries • (Chris or Shih-Chieh’s framework) • or try also to include the 95% CL limits? • (may need the LHC framework shown by Kalanandlast week)
