Search for a heavy resonance decaying to a top quark and a vector-like top quark at √s=13 TeV
(2017)Journal of High Energy PhysicsA search is presented for massive spin-1 Z′ resonances decaying to a top quark and a heavy vector-like top quark partner T. The search is based on a 2.6 fb−1 sample of proton-proton collisions at 13 TeV collected with the CMS detector at the LHC. The analysis is optimized for final states in which the T quark decays to a W boson and a bottom quark. The focus is on all-jet final states in which both the W boson and the top quark decay into ...Journal Article -
Measurement of the tt¯ production cross section using events with one lepton and at least one jet in pp collisions at s√ = 13 TeV
(2017)Journal of High Energy PhysicsA measurement of the tt¯ production cross section at s√=13 TeV is presented using proton-proton collisions, corresponding to an integrated luminosity of 2.2 fb−1, collected with the CMS detector at the LHC. Final states with one isolated charged lepton (electron or muon) and at least one jet are selected and categorized according to the accompanying jet multiplicity. From a likelihood fit to the invariant mass distribution of the isolated ...Journal Article -

Search for single production of a heavy vector-like T quark decaying to a Higgs boson and a top quark with a lepton and jets in the final state
(2017)Physics Letters BA search for single production of vector-like top quark partners (T) decaying into a Higgs boson and a top quark is performed using data from pp collisions at a centre-of-mass energy of 13 TeV collected by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 2.3 fb−1. The top quark decay includes an electron or a muon while the Higgs boson decays into a pair of b quarks. No significant excess over standard model ...Journal Article -
Measurement of the top quark mass in the dileptonic tt¯ decay channel using the mass observables Mbℓ, MT2, and Mbℓν in pp collisions at s√=8 TeV
(2017)Physical Review DA measurement of the top quark mass (Mt) in the dileptonic t¯t decay channel is performed using data from proton-proton collisions at a center-of-mass energy of 8 TeV. The data was recorded by the CMS experiment at the LHC and corresponds to an integrated luminosity of 19.7±0.5 fb−1. Events are selected with two oppositely charged leptons (ℓ=e, μ) and two jets identified as originating from b quarks. The analysis is based on three kinematic ...Journal Article -
Searches for W' bosons decaying to a top quark and a bottom quark in proton-proton collisions at 13TeV
(2017)Journal of High Energy PhysicsSearches are presented for heavy gauge bosons decaying into a top and a bottom quark in data collected by the CMS experiment at s √ s = 13 TeV that correspond to an integrated luminosity of 2.2 and 2.6 fb−1 in the leptonic and hadronic analyses, respectively. Two final states are analyzed, one containing a single electron, or muon, and missing transverse momentum, and the other containing multiple jets and no electrons or muons. No ...Journal Article -
Search for new phenomena in events with high jet multiplicity and low missing transverse momentum in proton–proton collisions at √s = 8 TeV
(2017)Physics Letters BA dedicated search is presented for new phenomena in inclusive 8- and 10-jet final states with low missing transverse momentum, with and without identification of jets originating from b quarks. The analysis is based on data from proton–proton collisions corresponding to an integrated luminosity of 19.7fb−1 collected with the CMS detector at the LHC at s=8TeV. The dominant multijet background expectations are obtained from low jet ...Journal Article -
Suppression of ϒ(1S), ϒ(2S), and ϒ(3S) quarkonium states in PbPb collisions at √sNN = 2.76 TeV
(2017)Physics Letters BThe production yields of ϒ(1S), ϒ(2S), and ϒ(3S) quarkonium states are measured through their decays into muon pairs in the CMS detector, in PbPb and pp collisions at the centre-of-mass energy per nucleon pair of 2.76 TeV. The data correspond to integrated luminosities of 166μb−1 and 5.4pb−1 for PbPb and pp collisions, respectively. Differential production cross sections are reported as functions of ϒ rapidity y up to 2.4, and transverse ...Journal Article -

Measurement of the jet mass in highly boosted tt¯ events from pp collisions at √s=8 TeV
(2017)The European Physical Journal CThe first measurement of the jet mass mjet of top quark jets produced in tt¯ events from pp collisions at s√=8TeV is reported for the jet with the largest transverse momentum pT in highly boosted hadronic top quark decays. The data sample, collected with the CMS detector, corresponds to an integrated luminosity of 19.7fb−1. The measurement is performed in the lepton+jets channel in which the products of the semileptonic decay t→bW with ...Journal Article
