Abstract	This document summarises the proposal of the LHC Dark Matter Working Group on how to present LHC results on $s$-channel simplified dark matter models and to compare them to direct (indirect) detection experiments.

$95\% CL exclusion contours in the mass-mass plane for a simplified model with a vector mediator, Dirac DM and couplings $\gq = 0.25$ and $\gDM = 1$. The black solid~(dashed) curve shows the median of the observed (expected) limit, while the yellow curves indicate an example of the uncertainties on the observed bound. A minimal width is assumed and the excluded parameter space is to the bottom-left of all contours. The dotted magenta curve corresponds to the parameters where the correct DM relic abundance is obtained from standard thermal freeze-out for the chosen couplings. DM is overproduced to the bottom-right of the curve. The shown LHC results are intended for illustration only and are not based on real data.$

$A comparison of LHC results to the $\mDM$--$\hspace{0.25mm} \sigma_{\rm{SI}}$ (a) and $\mDM$--$\hspace{0.25mm} \sigma_{\rm{SD}}$ (b) planes. Unlike in the mass-mass plane, the limits are shown at 90\%~CL. The LHC contour in the~SI~(SD) plane is for a vector (axial-vector) mediator, Dirac DM and couplings $\gq=0.25$ and $\gDM=1$. The LHC SI exclusion contour is compared with the LUX, CDMSLite and CRESST-II limits, which are the most constraining in the shown mass range. The SD exclusion contour constrains the DM-proton cross section and is compared with limits from the PICO experiments, the IceCube limit for the $t\bar{t}$ annihilation channel and the Super-Kamiokande limit for the $b\bar{b}$ annihilation channel. The depicted LHC results are intended for illustration only and are not based on real data.$ Show more plots
