Meeting with representativesfrom the three TDR upgrade projects (Pixels, HCAL and L1-Trig) and the two Task Forces (Phase II Track-rigger and Forward Calorimetry), the upgrade cross-organization coordinators (Offline, Computing and PPD), and the and POGs/PAG conveners
Intro and goals for the meeting (10min)
To overview status/plans for simulation work in support of the TDRs and TFs, with main focus on TDRs, and to discuss physics benchmarks and goals for follow-up Workshop Meeting in April
Phase 1 upgrades will be implemented 2016-2018, but must perform THROUGH LS3
The physics program in the year 2016, 2018, 2020, 2024 cannot be fully defined, so justification for upgrades must be established by
“generic” performance improvement for upgraded detector compared to (degraded) present detector) – studies with simulation of objects (particle gun, jets…)
Benchmark with a limited few physics channels (two per TDR?) which are representative of the gains expected
Simulation must have future-realistic PU conditions. Benchmark with a limited set of conditions to allow comparison of present and pre/post LS2 periods:
1E34@25ns ~ 5E33@50ns ~ 25 PU ~ 2012 conditions
2E34@25ns ~ 1E34@50ns ~ 50 PU
4E34@25ns ~ 2E34@50ns ~ 100 PU
Benchmark the present and the upgraded detectors
Reports from Upgrade Projects (80min)
TDRs : Pixel/HCAL/L1Trigger(20min each including discussion)
Brief summary of the upgrade concept and target benefits
Timescale and goals for the TDR
Status of simulation code (fastsim/mixedsim/fullsim) and studies. What outstanding issues?
Discuss physics benchmarks and requests for Physics Coordination
Reports from Physics Coordination(30min)
Status of studies and issues with current data/MC at high-PU
Issues for simulation/reconstruction, L1/HLT, physics analyses
Can present analyses and high-PU studies provide benchmarks andbe extended to higher pile-up to provide reference for current detector performance (eg high-PU performance task force…) with MC, data-mixing…
Proposal for physics benchmark channels
Specific to each TDR? Common across the detector upgrades?
What outstanding questions/work needed to establish a short list of physics benchmark channels
Discussion(30min to complete in 2.5hr)
Focus the near-term efforts on the TDRs – what needs to be done?
Meanwhile – ongoing efforts for TFs (capitalizes on TDR studies?)
How to proceed towards common code/releases and production
Goals for a workshop in early April, and what has to happen between now and then
