Dedicate to discuss the summary plots for LHCP 2017
Ad-hoc LHC EWK Multi-boson Meeting to discuss summary plots: https://indico.cern.ch/event/636276/
*The following summary concentrates on action items. Each action item is either to be followed up NOW or in the FUTURE, which is indicated in the note as well*
Summary of specific discussions on Carsten's slides:
Page 3-4: limit plots on fT,i and fM,i parameters
(NOW) Agreed to use solid limit lines for all the processes
(FUTURE) To make the "sensitive" limits more visible, don't show "insensitive" limits in the plot in the future
The "insensitive" limits are those which are 10 times larger than the most stringent limits on the same canvas
This will be the baseline strategy in the future
If speakers / conveners at certain points are not happy with some results being removed due to this reason, we could create a temporary version of these plots to include limits from requested processes
(FUTURE) Other possibilities to further improve the plotting style and presentation
Sort the parameters into several categories according to their different sensitive processes and show in different plots
Or still show all the parameters in one plot, but scale certain parameter limits by a constant (x10, x100, …)
(FUTURE) Page 4, fM,i limits: to resolve the inconsistency between ATLAS and CMS on WVg and gg->WW limits; to follow up with Marc-Andre, Matt and etc.
More information could be seen on page 9 under https://indico.cern.ch/event/574355/contributions/2331973/attachments/1351994/2041063/LHCEWWG-Pleier-aGClimit-summaries-101016.pdf
Page 5-8: limit plots on aTGCs
(FUTURE) Plan to add limit plots on EFT parameters
Page 6, limit plot on charged aTGCs
(NOW) to make the legend texts less crowded
(FUTURE) break down the plot into three in the future: 1) Delta Kappa_Z and Delta g1_Z; 2) Delta Kappa_gamma and Delta g1_gamma; 3) Lamda_Z
Still follow the LEP scenario. Lamda_Z corresponds to higher dimension operator in EFT parametrization. Showing Z and gamma parameters separately could be beneficial to emphasize the different contributing processes
(FUTURE) If needed, add details on the limit conversion and decay channels into the captions
(FUTURE) Add a vertical line at limit = 0
Page 7, limits from Zgamma channel
(NOW) To add back 7 TeV Zgamma limits
Page 8, limits from ZZ channel
(NOW) To drop 7 TeV individual limits, and only show the 7 TeV ATLAS+CMS combination
Page 6+7+8
If there are unitarized limits available and we plan to show, choose at most one unitarization scale to show in the plots
Summary of general discussions / proposals:
Preliminary Approval Policy for the Summary Plots
To use a dedicated mailing list and a public twiki for the summary plots
Mailing list: LHC-EWWG-MB-SummaryPlot@cern.ch
Twiki: https://twiki.cern.ch/twiki/bin/view/LHCPhysics/LHCEW
Once the updated summary plots are prepared, circulate them in the mailing list for three working days
The following members should review the plots: ATLAS/CMS contacts for the LHC EW MB group; ATLAS/CMS contacts for the Summary Plots; ATLAS/CMS EW Conveners
Other members are welcomed to post comments as well
After the circulation, improve the plots according to the comments
If no further issues, the plots are approved and can be labeled as "LHC EW Group". They will be put in Twiki as well.
If needed, organize a dedicated meeting to discuss remaining issues
More general comments on the plots
(NOW) Need to prepare captions for these plots; and if needed, add extra information about decay channels or limit conversions in the captions
(FUTURE) Plan to explicitly store different versions (tagged using the produced date) of the summary plots in the Twiki
(NOW) In general, make sure that only the best limit is shown for each process at each sqrt(S) from each experiment.
