Today's meeting: big audience! Thanks a lot everyone for joining! 

We went through the EF01 presentation, paper draft, tracker studies and the plot Patrick Maede just sent us. All the material is uploaded on the agenda.

EF01 presentation: Received feedback from Patrick Maede right after today's EF01 meeting with a plot of strange Yukawa coupling bounds from multi-higgs at the HL-LHC showing that our limits will be pushing the reach beyond LHC. Also EF01 conveners were happy with the work and said we gave enough work to the theorists to think about models :-)

Action items to converge on the paper draft:

• H->cs: won't be included in this first draft (Whizard generation works, but the actual events still need to be generated), but the work should continue and we can always update the paper on the arxiv later (or add a dedicated interpretation of this analysis) 
  • When we talk to Patrick abut the limits above, Rui & Su Dong will also join to discuss about interesting/meaningful mass points to generate
• RICH: add a summary in the main body and more details in the appendix (Jerry already has about 10 pages, perfect for now)
  • Key plots to have: PID perfomance for k/pi vs momentum & dependence on magnetic field (related to track-bending effects on Cherenkov resolution)
• Detector section: add also statements about the compact tracker (how compact to make space for the RICH and keep the magnetic field as is)
  • Chris can help writing it, Markus' inputs will be useful as well. 
  • Can consider adding some of the Analytical studies I made on tracking resolutions before the break (see slides on the agenda) either in the main body or appendix, but need to make clear that the 5um resolution used there is to be proven!
• Jingyu is studying a modern network for flavour tagging which brought in improvements in btagging in CMS and he is willing to try it out for the strange tagger here. Should be possible in 1 month timescale. If ready, we can ad it as a comparison to the tagger, without re-running the whole analysis chain because that would not arrive on time
• Strange tagging section in the paper: add plot that shows the momentum range relevant for stag (we already have it and we have always shown it in slides, we just forgot to put it in the paper :-) ). Add information on most discriminant input variables for stag (consider adding all inputs in the appendix).
• Author list to be updated before arxiv submission of course
