Search for t t ¯ H production in the H → b b ¯ decay channel with leptonic t t ¯ decays in proton-proton collisions at √s=13 TeV
(2019)Journal of High Energy PhysicsA search is presented for the associated production of a standard model Higgs boson with a top quark-antiquark pair (tt¯H), in which the Higgs boson decays into a b quark-antiquark pair, in proton-proton collisions at a centre-of-mass energy s√=13 TeV. The data correspond to an integrated luminosity of 35.9 fb−1 recorded with the CMS detector at the CERN LHC. Candidate tt¯H events are selected that contain either one or two electrons or ...Journal Article -
Search for new particles decaying to a jet and an emerging jet
(2019)Journal of High Energy PhysicsA search is performed for events consistent with the pair production of a new heavy particle that acts as a mediator between a dark sector and normal matter, and that decays to a light quark and a new fermion called a dark quark. The search is based on data corresponding to an integrated luminosity of 16.1 fb−1 from proton-proton collisions at s√=13 TeV collected by the CMS experiment at the LHC in 2016. The dark quark is charged only ...Journal Article -
Search for the pair production of light top squarks in the e ±μ ∓ final state in proton-proton collisions at √s=13 TeV
(2019)Journal of High Energy PhysicsA search for the production of a pair of top squarks at the LHC is presented. This search targets a region of parameter space where the kinematics of top squark pair production and top quark pair production are very similar, because of the mass difference between the top squark and the neutralino being close to the top quark mass. The search is performed with 35.9 fb−1 of proton-proton collisions at a centre-of-mass energy of s√=13 TeV, ...Journal Article -

Search for dark matter produced in association with a single top quark or a top quark pair in proton-proton collisions at √s=13 TeV
(2019)Journal of High Energy PhysicsA search for dark matter produced in association with top quarks in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The data set used corresponds to an integrated luminosity of 35.9 fb−1 recorded with the CMS detector at the LHC. Whereas previous searches for neutral scalar or pseudoscalar mediators considered dark matter production in association with a top quark pair only, this analysis also includes production ...Journal Article -
Search for pair production of second-generation leptoquarks at s =13 TeV
(2019)Physical Review DA search for pair production of second-generation leptoquarks is performed using proton-proton collision data collected at √s=13 TeV in 2016 with the CMS detector at the CERN LHC, corresponding to an integrated luminosity of 35.9 fb−1. Final states with two muons and two jets, or with one muon, two jets, and missing transverse momentum are considered. Second-generation scalar leptoquarks with masses less than 1530(1285) GeV are excluded ...Journal Article -
Search for nonresonant Higgs boson pair production in the b b ¯ b b ¯ final state at √s = 13 TeV
(2019)Journal of High Energy PhysicsResults of a search for nonresonant production of Higgs boson pairs, with each Higgs boson decaying to a bb¯¯¯ pair, are presented. This search uses data from proton-proton collisions at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1, collected by the CMS detector at the LHC. No signal is observed, and a 95% confidence level upper limit of 847 fb is set on the cross section for standard model ...Journal Article -
Search for top quark partners with charge 5/3 in the same-sign dilepton and single-lepton final states in proton-proton collisions at √s=13 TeV
(2019)Journal of High Energy PhysicsA search for the pair production of heavy fermionic partners of the top quark with charge 5/3 (X5/3) is performed in proton-proton collisions at a center-of-mass energy of 13 TeV with the CMS detector at the CERN LHC. The data sample analyzed corresponds to an integrated luminosity of 35.9 fb−1. The X5/3 quark is assumed always to decay into a top quark and a W boson. Both the right-handed and left-handed X5/3 couplings to the W boson are ...Journal Article -
Inclusive search for supersymmetry in pp collisions at √s=13 TeV using razor variables and boosted object identification in zero and one lepton final states
(2019)Journal of High Energy PhysicsAn inclusive search for supersymmetry (SUSY) using the razor variables is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 35.9 fb−1, collected with the CMS experiment in 2016 at a center-of-mass energy of s√=13 TeV. The search looks for an excess of events with large transverse energy, large jet multiplicity, and large missing transverse momentum. The razor kinematic variables are ...Journal Article
