title: "Figure 9b observed contour" of "Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks"

description: Figure 9b (upper right). Observed exclusion region at 95% CL.
description: CERN-LHC. CMS. A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance pT_miss in transverse momentum. The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, and correspond to an integrated luminosity of 35.9 fb−1. Search regions are defined in terms of the multiplicity of bottom quark jet and top quark candidates, the pT_miss, the scalar sum of jet transverse momenta, and the mT2 mass variable. No statistically significant excess of events is observed relative to the expectation from the standard model. Lower limits on the masses of supersymmetric particles are determined at 95% confidence level in the context of simplified models with top quark production. For a model with direct top squark pair production followed by the decay of each top squark to a top quark and a neutralino, top squark masses up to 1020 GeV and neutralino masses up to 430 GeV are excluded. For a model with pair production of gluinos followed by the decay of each gluino to a top quark-antiquark pair and a neutralino, gluino masses up to 2040 GeV and neutralino masses up to 1150 GeV are excluded. These limits extend previous results.

description: CERN-LHC. Search for top squarks and dark matter particles in opposite-charge dilepton final states at sqrt(s) = 13 TeV

A search for new physics is presented in final states with two oppositely charged leptons (electrons or muons), jets identified as originating from b quarks, and missing transverse momentum (pTmiss).
The search uses proton-proton collision data at 13 TeV amounting to 35.9 $fb^{−1}$ of integrated luminosity collected using the CMS detector in 2016.
Hypothetical signal events are efficiently separated from the dominant ttbar background with requirements on pTmiss and transverse mass variables.
No significant deviation is observed from the expected background.
Exclusion limits are set in the context of simplified supersymmetric models with pair-produced top squarks.
For top squarks, decaying exclusively to a top quark and a neutralino, exclusion limits are placed at 95% confidence level on the mass of the lightest top squark up to 800 GeV and on the lightest neutralino up to 360 GeV.
These results, combined with searches in the single-lepton and all-jet final states, raise the exclusion limits up to 1050 GeV for the lightest top squark and up to 500 GeV for the lightest neutralino.
For top squarks undergoing a cascade decay through charginos and sleptons, the mass limits reach up to 1300 GeV for top squarks and up to 800 GeV for the lightest neutralino.
The results are also interpreted in a simplified model with a dark matter (DM) particle coupled to the top quark through a scalar or pseudoscalar mediator.
For light DM, mediator masses up to 100 (50) GeV are excluded for scalar (pseudoscalar) mediators.
The result for the scalar mediator achieves some of the most stringent limits to date in this model.
