Measurement of the W-boson helicity in top-quark decays from t(t)over-bar production in lepton plus jets events in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2013-10)
The W-boson helicity fractions in top-quark decays are measured with TeX events in the lepton+jets final state, using proton-proton collisions at a centre-of-mass energy of 7 TeV, collected in 2011 with the CMS detector ...
Measurement of the t t ¯ production cross section in the eμ channel in proton-proton collisions at √s = 7 and 8 TeV
(Springer Nature, 2016-08)
The inclusive cross section for top quark pair production is measured in proton-proton collisions at s√=7s=7 and 8 TeV, corresponding to 5.0 and 19.7 fb−1, respectively, with the CMS experiment at the LHC. The cross ...
Observation of top quark pairs produced in association with a vector boson in pp collisions at root s=8 TeV
(Springer Nature, 2016-01)
Measurements of the cross sections for top quark pairs produced in association with a W or Z boson are presented, using 8 TeV pp collision data corresponding to an integrated luminosity of 19.5 fb−1, collected by the CMS ...
Search for anomalous single top quark production in association with a photon in pp collisions at √s = 8 TeV
(2016-04)
The result of a search for flavor changing neutral currents (FCNC) through single top quark production in association with a photon is presented. The study is based on proton-proton collisions at a center-of-mass energy ...
Measurement of top quark polarisation in t-channel single top quark production
(2016-04)
A first measurement of the top quark spin asymmetry, sensitive to the top quark polarisation, in t-channel single top quark production is presented. It is based on a sample of pp collisions at a centre-of-mass energy of 8 ...
Search for a heavy resonance decaying to a top quark and a vector-like top quark at √s=13 TeV
(Springer International Publishing, 2017-09-13)
A 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 ...
Search for electroweak production of a vector-like quark decaying to a top quark and a Higgs boson using boosted topologies in fully hadronic final states
(Springer International Publishing, 2017)
A search is performed for electroweak production of a vector-like top quark partner T of charge 2/3 in association with a standard model top or bottom quark, using 2.3 fb−1 of proton-proton collision data at s√=13s=13 ...
Search for standard model production of four top quarks in the lepton + jets channel in pp collisions at √s = 8 TeV
(Springer International Publishing, 2014-11)
A search is presented for standard model (SM) production of four top quarks (tt¯tt¯)(tt¯tt¯) in pp collisions in the lepton + jets channel. The data correspond to an integrated luminosity of 19.6 fb−1 recorded at a ...
Measurement of the semileptonic t t ¯ + γ production cross section in pp collisions at √s=8 TeV
(Springer International Publishing, 2017-10-02)
A measurement of the cross section for top quark-antiquark ( tt¯tt¯ ) pairs produced in association with a photon in proton-proton collisions at s√=8s=8 TeV is presented. The analysis uses data collected with the CMS ...
