Search for production of Higgs boson pairs in the four b quark final state using large-area jets in proton-proton collisions at root s 13 TeV
(2019)Journal of High Energy PhysicsA search is presented for pair production of the standard model Higgs boson using data from proton-proton collisions at a centre-of-mass energy of 13 TeV, collected by the CMS experiment at the CERN LHC in 2016, and corresponding to an integrated luminosity of 35.9 fb−1. The final state consists of two b quark-antiquark pairs. The search is conducted in the region of phase space where one pair is highly Lorentz-boosted and is reconstructed ...Journal Article -
Measurements of t t ¯ differential cross sections in proton-proton collisions at √s=13 TeV using events containing two leptons
(2019)Journal of High Energy PhysicsMeasurements of differential top quark pair tt¯ cross sections using events produced in proton-proton collisions at a centre-of-mass energy of 13 TeV containing two oppositely charged leptons are presented. The data were recorded by the CMS experiment at the CERN LHC in 2016 and correspond to an integrated luminosity of 35.9 fb−1. The differential cross sections are presented as functions of kinematic observables of the top quarks and ...Journal Article -
Search for new physics in final states with a single photon and missing transverse momentum in proton-proton collisions at √s=13 TeV
(2019)Journal of High Energy PhysicsA search is conducted for new physics in final states containing a photon and missing transverse momentum in proton-proton collisions at √s=13 TeV, using the data collected in 2016 by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb−1. No deviations from the predictions of the standard model are observed. The results are interpreted in the context of dark matter production and models containing extra ...Journal Article -
Search for excited leptons in ℓℓγ final states in proton-proton collisions at √s=13 TeV
(2019)Journal of High Energy PhysicsA search is presented for excited electrons and muons in ℓℓγ final states at the LHC. The search is based on a data sample corresponding to an integrated luminosity of 35.9 fb−1 of proton-proton collisions at a center-of-mass energy of 13 TeV, collected with the CMS detector in 2016. This is the first search for excited leptons at s√ = 13 TeV. The observation is consistent with the standard model background prediction, and the most stringent ...Journal Article -
Search for resonant t t ¯ production in proton-proton collisions at √s=13 TeV
(2019)Journal of High Energy PhysicsA search for a heavy resonance decaying into a top quark and antiquark (tt¯) pair is performed using proton-proton collisions at s√=13 TeV. The search uses the data set collected with the CMS detector in 2016, which corresponds to an integrated luminosity of 35.9 fb−1. The analysis considers three exclusive final states and uses reconstruction techniques that are optimized for top quarks with high Lorentz boosts, which requires the use ...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 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 -
