Limits on the universal coupling g'_q between a leptophobic Z′ boson and quarks [arXiv:1611.03568] from various CMS dijet analyses. The expected limits are shown in dashed lines, and the corresponding observed limits are shown in solid lines. The hashed areas show the direction of the excluded area from the observed limits. The grey dashed lines show the g'_q values at fixed values of Γ_Z′/M_Z′. Most of the analyses, with the exception of Dijet χ and Broad Dijet, assume that the intrinsic width is negligible compared to the experimental resolution, and hence are valid for Γ_Z′ /M_Z′ ≲ 10%. The tt resonance analysis is valid for Γ_Z′ /M_Z′ ≲ 5%, the Broad Dijet analysis is valid for Γ_Z′ /M_Z′ ≲ 30%, and the Dijet χ analysis is valid for Γ_Z′ /M_Z′ ≲ 100%. | |

95% CL observed and expected exclusion regions in mMed-mDM plane for di-jet searches and different MET based DM searches from CMS in the lepto-phobic Axial-vector model. Following the recommendation of the LHC DM working group ([arXiv:1603.04156], [arXiv:1703.05703]), the exclusions are computed for a universal quark coupling of g_q = 0.25 and for a DM coupling of gDM = 1.0. It should also be noted that the absolute exclusion of the different searches as well as their relative importance, will strongly depend on the chosen coupling and model scenario. Therefore, the exclusion regions, relic density contours, and unitarity curve shown in this plot are not applicable to other choices of coupling values or model. | |

A comparison of CMS results to the mDM-sigma_SD plane. Unlike in the mass-mass plane, the limits are shown at 90% CL. The CMS contour in the SD plane is for an Axial-vector mediator, Dirac DM and couplings g_q = 0.25 and gDM = 1.0. The SD exclusion contour is compared with limits from PICASSO and PICO experiments, the IceCube limit for the ttbar, bbbar annihilation channels, and the Super-Kamiokande limit for the bbbar annihilation channel. It should be noted that the CMS limits do not include a constraint on the relic density and also the absolute exclusion of the different CMS searches as well as their relative importance will strongly depend on the chosen coupling and model scenario. Therefore, the shown CMS exclusion regions in this plot are not applicable to other choices of coupling values or models. | |

The CMS SI exclusion contour is compared with the XENON1T 2017, LUX 2016, PandaX -II 2016 , CDMSLite 2015 and CRESST-II 2015 limits, which constitutes the strongest documented constraints in the shown mass range. It should be noted that the CMS limits do not include a constraint on the relic density and also the absolute exclusion of the different CMS searches as well as their relative importance will strongly depend on the chosen coupling and model scenario.

Observed and expected gluino mass exclusions at 95% CL (indicated, respectively, by solid and dashed contours) for simplified models that assume the production of pairs of long-lived gluinos that each form an R-hadron bound state, before decaying via highly virtual light-flavour squarks to the neutralino and a quark-antiquark pair. The mass exclusions are presented as a function of the gluino proper decay length cτ and lifetime τ. The mass exclusions are shown as obtained from three searches under various model assumptions, as indicated in the figure legend. The charge suppressed scenario assumes that the R-hadron does not undergo nuclear interactions with the detector material. The fraction f_g ̃g specifies the probability that the R-hadron is formed as a gluino-gluon bound state. Exclusions for scenarios that involve the prompt decay of the gluino or a stable gluino are also indicated by circular markers. |
