We consider minimal dark matter scenarios featuring momentum-dependent couplings of the dark sector to the Standard Model. We derive constraints from existing LHC searches in the monojet channel, estimate the future LHC sensitivity for an integrated luminosity of 300 fb −1 , and compare with models exhibiting conventional momentumindependent interactions with the dark sector. In addition to being well motivated by (composite) pseudo-Goldstone dark matter scenarios, momentum-dependent couplings are interesting as they weaken direct detection constraints. For a specific dark matter mass, the LHC turns out to be sensitive to smaller signal cross-sections in the momentum-dependent case, by virtue of the harder jet transverse-momentum distribution.

“…We note that we compared the CheckMATE results with those obtained by the equivalent analysis implementations in MadAnalysis 5 [47,48] (recast codes [49,50]) and Rivet 2.5 [51] for a couple of representative mass choices and found agreement at the level of 20% within all three tools.…”

Simplified dark matter models with a spin-2 mediator at the LHC

et al. 2017

We consider simplified dark matter models where a dark matter candidate couples to the standard model (SM) particles via an s-channel spin-2 mediator, and study constraints on the model parameter space from the current LHC data. Our focus lies on the complementarity among different searches, in particular monojet and multijet plus missing-energy searches and resonance searches. For universal couplings of the mediator to SM particles, missing-energy searches can give stronger constraints than W W , Z Z, dijet, dihiggs, tt, bb resonance searches in the low-mass region and/or when the coupling of the mediator to dark matter is much larger than its couplings to SM particles. The strongest constraints, however, come from diphoton and dilepton resonance searches. Only if these modes are suppressed, missingenergy searches can be competitive in constraining dark matter models with a spin-2 mediator.

“…The events are then passed to Pythia8 [108] for parton showering and hadronization, and the fast detector simulation in Delphes3 (ATLAS settings) [109] is used to include the detector effects. Finally, events are analyzed with MadAnalysis5 [110][111][112].…”

Higgs bosons pair production is well known for its sensitivity to probing the sign and size of Higgs boson self coupling, providing a way to determine whether there is an extended Higgs sector. The Georgi-Machacek (GM) model extends the Standard Model (SM) with an SU(2) L triplet scalar field that has one real and one complex components. The Higgs self coupling now has a wider range than that in the SM, with even the possibility of a sign flip. The new heavy singlet Higgs boson H 0 1 can contribute to s-channel production of the hh pairs. In this work, we study non-resonant/resonant Higgs boson pair productions pp → hh and pp → H 0 1 → hh, focusing exclusively on the contribution of H 0 1 . We show the sensitivity for Higgs boson pair production searches at the 13-TeV LHC with the luminosities of 3.2, 30 and 100 fb −1 .
