| Abstract: A search for supersymmetry (SUSY) is performed in final states comprising one or more jets and missing transverse momentum using data from proton-proton collisions at a centre-of-mass energy of 13 TeV. The data were recorded with the CMS detector at the CERN LHC in 2016 and correspond to an integrated luminosity of 35.9 fb$^{-1}$. The number of signal events is found to agree with the expected background yields from standard model processes. The results are interpreted in the context of simplified models of SUSY that assume the production of gluino or squark pairs and their prompt decay to quarks and the lightest neutralino. The masses of bottom, top, and mass-degenerate light-flavour squarks are probed up to 1050, 1000, and 1325 GeV, respectively. The gluino mass is probed up to 1900, 1650, and 1650 GeV when the gluino decays via virtual states of the aforementioned squarks. The strongest mass bounds on the neutralinos from gluino and squark decays are 1150 and 575 GeV, respectively. The search also provides sensitivity to simplified models inspired by split SUSY that involve the production and decay of long-lived gluinos. Values of the proper decay length $ {c\tau_{0}} $ from 10$ ^{-3} $ to 10$ ^{5} $ mm are considered, as well as a metastable gluino scenario. Gluino masses up to 1750 and 900 GeV are probed for $ {c\tau_{0}} = $ 1 mm and for the metastable state, respectively. The sensitivity is moderately dependent on model assumptions for $ {c\tau_{0}} > $ 1 m. The search provides coverage of the $ {c\tau_{0}} $ parameter space for models involving long-lived gluinos that is complementary to existing techniques at the LHC. | ||

Figure 3:
Observed and expected mass exclusions at 95% CL (indicated, respectively, by solid and dashed contours) for various families of simplified models. The upper subfigure summarises the mass exclusions for five model families that involve the direct pair production of squarks. The first scenario considers the pair production and decay of bottom squarks (T2bb). Two scenarios involve the production and decay of top squark pairs (T2tt and T2cc). The grey shaded region denotes T2tt models that are not considered for interpretation. Two further scenarios involve, respectively, the production and decay of light-flavour squarks, with different assumptions on the mass degeneracy of the squarks as described in the text (T2qq_8fold and T2qq_1fold). The lower subfigure summarises three scenarios that involve the production and prompt decay of gluino pairs via virtual squarks (T1bbbb, T1tttt, and T1qqqq). A final scenario involves the production of gluinos that are assumed to be metastable on the detector scale (T1qqqqLL). |

| Summary |
|
A search for supersymmetry with the CMS experiment is reported, based on a data sample of pp collisions collected in 2016 at $\sqrt{s} = $ 13 TeV that corresponds to an integrated luminosity of 35.9 $\pm$ 0.9 fb$^{-1}$ . Final states with jets and significant missing transverse momentum $ \vec{p}_{\mathrm{T}}^{\text{miss}} $, as expected from the production and decay of massive gluinos and squarks, are considered. Signal events are categorized according to the number of reconstructed jets, the number of jets identified as originating from bottom quarks, and the scalar and vector sums of the transverse momenta of jets. The standard model background is estimated from a binned likelihood fit to event yields in the signal region and data control samples. The observed yields in the signal region are found to be in agreement with the expected contributions from standard model processes. Supplemental material is provided to aid further interpretation of the result in Appendix. Limits are determined in the parameter spaces of simplified models that assume the production and prompt decay of gluino or squark pairs. The strongest exclusion bounds (95% confidence level) for squark masses are 1050, 1000, and 1325 GeV for bottom, top, and mass-degenerate light-flavour squarks, respectively. The corresponding mass bounds on the neutralino $\tilde{\chi}^0_1$ from squark decays are 500, 400, and 575 GeV. The gluino mass is probed up to 1900, 1650, and 1650 GeV when the gluino decays via virtual states of the aforementioned squarks. The strongest mass bound on the $\tilde{\chi}^0_1$ from the gluino decay is 1150 GeV. Sensitivity to simplified models inspired by split supersymmetry is also demonstrated. These models assume the production of long-lived gluino pairs that decay to final states containing displaced jets and $ \vec{p}_{\mathrm{T}}^{\text{miss}} $ from the undetected $\tilde{\chi}^0_1 $ particles. The long-lived gluino, with an assumed proper decay length ${c\tau_{0}} $, is expected to hadronize with SM particles and form a bound state known as an R-hadron. The model-dependent matter interactions of R-hadrons are not considered by default. The sensitivity of this search is only moderately dependent on these matter interactions for models with ${c\tau_{0}} > $ 1 m, while no dependence is found for models with ${c\tau_{0}} $ below 1 m. Models that assume a $\tilde{\chi}^0_1$ mass of 100 GeV and gluino masses up to 1600 GeV are excluded for a proper decay length ${c\tau_{0}} $ below 0.1 mm. The bound on the gluino mass strengthens to 1750 GeV at ${c\tau_{0}} = $ 1 mm, before weakening to 900-1000 GeV for models with ${c\tau_{0}} > $ 10 m. For all values of ${c\tau_{0}} $ considered, the exclusion bounds on the gluino mass weaken to about 1 TeV when the difference between the gluino and $\tilde{\chi}^0_1$ mass is small. The search provides coverage of the ${c\tau_{0}} $ parameter space for models involving long-lived gluinos, such as the region ${c\tau_{0}} < $ 1 mm, that is complementary to the coverage provided by dedicated techniques at the LHC. |

Observed and expected mass exclusions at 95% CL (indicated, respectively, by solid and dashed contours) for simplified models with an intermediate squark. Five model families involve the direct pair production of squarks. The first scenario considers the pair production and decay of bottom squarks (T2bb). Two scenarios involve the production and decay of top squark pairs (T2tt and T2cc). The grey shaded region denotes T2tt models that are not considered for interpretation. Two further scenarios involve, respectively, the production and decay of light-flavour squarks, with different assumptions on the mass degeneracy of the squarks as described in the text (T2qq\_8fold and T2qq\_1fold). |

Counts of events in the signal region from data (solid markers), SM expectations with associated uncertainties (statistical and systematic, black histograms and shaded bands) as determined from the CR-only fit, and the predicted signal shape and uncertainty assuming a production cross section calculated at NLO+NLL accuracy for the T1qqqqLL benchmark model with $ {c\tau _{0}} =1$\nobreakspace {}mm, ($m_{\tilde{g}}$, $m_{{\tilde{\chi}^{0}_{1}}}) = $ (1800, 200) GeV (magenta histogram and shaded band), as a function of ${n_{\text {jet}}}$, $ {n_{\text {b}}}$, $ {H_{\text {T}}} $, and $ {H_{\mathrm {T}}^{\text {miss}}} $ using the simplified binning schema. The centre panel of each subfigure shows the ratios of observed counts and the SM expectations, while the lower panel shows the significance of deviations observed in data with respect to the SM expectations expressed in terms of the total uncertainty in the SM expectations. |
