“…In particular, we are interested in how the presence of R-parity-violating operators affects the well-known results for the R-parity-conserving CMSSM [20,22,172,173]. For this purpose we shall use the program CheckMATE [63][64][65]. As we saw in Sects.…”

We investigate the phenomenology of the MSSM extended by a single R-parity-violating coupling at the unification scale. For all R-parity-violating couplings, we discuss the evolution of the particle spectra through the renormalization group equations and the nature of the lightest supersymmetric particle (LSP) within the CMSSM, as an example of a specific complete supersymmetric model. We use the nature of the LSP to classify the possible signatures. For each possible scenario we present in detail the current LHC bounds on the supersymmetric particle masses, typically obtained using simplified models. From this we determine the present coverage of R-parity-violating models at the LHC. We find several gaps, in particular for a stau-LSP, which is easily obtained in R-parity-violating models. Using the program CheckMATE we recast existing LHC searches to set limits on the parameters of all R-parity-violating CMSSMs. We find that virtually all of them are either more strongly constrained or similarly constrained in comparison to the R-parity-conserving CMSSM, including theŪDD models. For each R-parity-violating CMSSM we then give the explicit lower mass bounds on all relevant supersymmetric particles.

“…As default we generate 25,000 events for every production process. The generated events are then fed into CheckMATE 2.0.7 [49,50], which uses Delphes 3.4.0 as detector simulation [51]. Given a specific experimental search, CheckMATE compares the number of events passing each signal region with the observed S95 limit obtained by the experiment via the parameter…”

Constraining sleptons at the LHC in a supersymmetric low-scale seesaw scenario

We consider a scenario inspired by natural supersymmetry, where neutrino data is explained within a lowscale seesaw scenario. We extend the Minimal Supersymmetric Standard Model by adding light right-handed neutrinos and their superpartners, the R-sneutrinos, and consider the lightest neutralinos to be higgsino-like. We consider the possibilities of having either an R-sneutrino or a higgsino as lightest supersymmetric particle. Assuming that squarks and gauginos are heavy, we systematically evaluate the bounds on slepton masses due to existing LHC data.

“…Several SRs are characterised by minimum jet multiplicity from two to six; / E T > 200 GeV is required for all SRs, while different thresholds are applied on jet momenta and on the azimuthal separation between jets and / E T . To reinterpret the above analyses in the context of our spin-2 mediator simplified DM model, we use Check-MATE2 [44], which is a public recasting tool providing confidence limits from simulated signal events and includes a number of 13 TeV analyses. We generate hadron-level signal samples by using the tree-level matrix-element plus partonshower (ME+PS) merging procedure.…”

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.
