[Rgc_analysis] Analysis results for RG-C jeopardy presentation

[Sebastian Kuhn]

Dear RGC-ers,

Tomorrow our weekly meeting will be pre-empted by the CLAS collaboration meeting. I will give a “dry run” presentation for the RG-C jeopardy defense on Thursday 6/27 at 9:20 a.m.. If any of you haven’t sent me your most up-to-date plots for the jeopardy yet, please do so by the end of today so I have a little time preparing my talk.

Thanks - Sebastian

Dear RGC-ers,

As you know, our jeopardy review is coming up in 4 weeks (precisely: Wednesday July 10, in the afternoon). We have a total of 30 minutes including questions, so I am aiming for a 20 min presentation = 20 slides max. I am planning to address mostly the same topics as our jeopardy update document - https://www.overleaf.com/project/65e725777c341f01c13f4d5d
For the presentation, I would like to ask you to prepare plots of the relevant observables with error bars based on the ENTIRE Summer 2022 data set (or as large a fraction of it as possible), with appropriately fine/multi-dimensional binning to show the information contained in those data, plus an estimate (either pseudo-data or the same data but with “shrunk error bars”) of what the entire RG-C 2022-23 data set will provide (just scale the error bars by the ratio for sqrt(integrated charge) for Summer and the entire run), as well as the expected error bars for the FULL 120 days assuming we get 40 more PAC days. For the latter, we should simply assume that the FOM (Pt^2 * Integrated lumi) will be roughly 75% of what we already collected (50% more beam time times better target polarization times slightly higher beam current), which would reduce the error bars further by a factor 0.8. (Anything else would be too complicated at this point, and also require extensive “haggling” about the exact split between different running conditions which I would like to postpone until we have a clearer indication of what we can expect).

Keep in mind that we can’t ask for “extra time” or “extra Physics” - so, at most 1 slide showing “interesting new observables that will become available” and the rest should be focused on the 8 approved channels (DIS, nDVCS, pDVCS, TMDs with pi, 2-pi, and K as well as p in target fragmentation and p-pi).
Please provide those plots to me in the next 2 weeks, and I will present a first draft of the slides 3 weeks from now (we should spend our entire RG-C meetings on June 25 and July 2 on the preparations for the PAC).

Thanks, and full speed ahead! - Sebastian
