Recommendations for labels in PUB note plots

The recommendations below are divided by projection type and refer to the final labels to be used for the public document. As usual during initial circulation the "Internal" corresponding label should be used, as usual.

- Smearing function studies:

ATLAS Simulation Preliminary
#sqrt{s}=14 TeV, 3000 fb^{-1}

- Extrapolation (using run-2 data):

ATLAS Preliminary
Projection from Run 2 data
#sqrt{s}=14 TeV, 3000 fb^{-1}

- Combination plots using both extrapolations as well as smearing function studies:

ATLAS Preliminary
#sqrt{s}=14 TeV, 3000 fb^{-1}
Simulation and Projections from Run 2 data

- HE-LHC projections: Same guidelines as above, depending on the projection study type, but replacing the center-of-mass energy and luminosity accordingly:

#sqrt{s}=27 TeV, 15 ab^{-1}

Technical information

Information on SW, MC samples, and analysis code (including smearing functions)

Detailed MC production information can be found here (mostly useful for MC contact people).

On going activities:

Information on existing upgrade samples:

Information on tags:

A set of detector performance functions (including smearing functions that account for detector resolution) can be used on truth objects to derive realistic detector-level quantities. These functions are described in UpgradePerformanceFunctions.

Information on Tracking with rel20 can be found here.

Information on correction factors for Phase-II upgrade used in extrapolations of Run-2 analyses are being collected here

Public results on upgrade (including LHC schedule)

Results are made public in form of PUBNOTES. The procedure for the PUB note approval can be found here. Under exceptional circumstances, results can be made public as PLOTS following the procedure outlined here
