Search for a heavy resonance decaying to a top quark and a vector-like top quark in the lepton + jets final state in pp collisions at √ s=13TeV
(2019)The European Physical Journal CA search is presented for a heavy spin-1 resonance Z′ decaying to a top quark and a vector-like top quark partner T in the lepton + jets final state. The search is performed using a data set of p p collisions at a centre-of-mass energy of 13TeV corresponding to an integrated luminosity of 35.9fb−1 as recorded by the CMS experiment at the CERN LHC in the year 2016. The analysis is optimised for final states arising from the T decay modes ...Journal Article -
Search for narrow Hγ resonances in proton-proton collisions at s =13 TeV
(2019)Physical Review LettersA search for heavy, narrow resonances decaying to a Higgs boson and a photon (Hγ) has been performed in proton-proton collision data at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1 collected with the CMS detector at the LHC in 2016. Events containing a photon and a Lorentz-boosted hadronically decaying Higgs boson reconstructed as a single, large-radius jet are considered, and the γ+jet invariant ...Journal Article -
Measurement of associated production of a W boson and a charm quark in proton–proton collisions at √s=13Te
(2019)The European Physical Journal CMeasurements are presented of associated production of a W boson and a charm quark (W+c) in proton–proton collisions at a center-of-mass energy of 13TeV. The data correspond to an integrated luminosity of 35.7fb−1 collected by the CMS experiment at the CERN LHC. The W bosons are identified by their decay into a muon and a neutrino. The charm quarks are tagged via the full reconstruction of D∗(2010)± mesons that decay via D∗(2010)±→D0+π±→K∓+π±+π±. ...Journal Article -

Search for heavy neutrinos and third-generation leptoquarks in hadronic states of two τ leptons and two jets in proton-proton collisions at √s=13 TeV
(2019)Journal of High Energy PhysicsA search for new particles has been conducted using events with two high transverse momentum τ leptons that decay hadronically and at least two energetic jets. The analysis is performed using data from proton-proton collisions at s√=13 TeV, collected by the CMS experiment at the LHC in 2016 and corresponding to an integrated luminosity of 35.9 fb−1. The observed data are consistent with standard model expectations. The results are interpreted ...Journal Article -
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 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 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
