Measurement of the t(t)over-bar production cross section in the e mu channel in proton-proton collisions at root s=7 and 8 TeV
(Journal of High Energy Physics, 2016)
The inclusive cross section for top quark pair production is measured in proton-proton collisions at root s = 7 and 8TeV, corresponding to 5.0 and 19.7 fb(-1), respectively, with the CMS experiment at the LHC. The cross ...
Search for associated production of a Z boson with a single top quark and for tZ flavour-changing interactions in pp collisions at root s=8 TeV
(Journal of High Energy Physics, 2017)
A search for the production of a single top quark in association with a Z boson is presented, both to identify the expected standard model process and to search for flavour changing neutral current interactions. The data ...
Search for top quark partners with charge 5/3 in proton-proton collisions at root s=13 TeV
(Journal of High Energy Physics, 2017)
A search for the production of heavy partners of the top quark with charge 5/3 (X-5/3) decaying into a top quark and a W boson is performed with a data sample corresponding to an integrated luminosity of 2.3 fb(-1), collected ...
Measurement of the mass of the top quark in decays with a J/psi meson in pp collisions 8 Tev
(Journal of High Energy Physics, 2016)
A first measurement of the top quark mass in the decay channel t - GT (W - GT l nu)(b - GT J/psi + X - GT mu(+) + mu(-) + X) is presented. The analysis uses events selected from the proton-proton collisions recorded by the ...
Measurement of the t(t)over-bar production cross section using events with one lepton and at least one jet in pp collisions at root s=13 TeV

A measurement of the t (t) over bar production cross section at root 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 ...
Search for CP violation in t(t)over-bar production and decay in proton-proton collisions at root s=8 TeV
(Journal of High Energy Physics, 2017)
The results of a first search for CP violation in the production and decay of top quark-antiquark (t (t) over bar) pairs are presented. The search is based on asymmetries in T-odd, triple-product correlation observables, ...
Measurement of the semileptonic t(t)over-bar + gamma production cross section in pp collisions at root s=8 TeV

A measurement of the cross section for top quark-antiquark (t (t) over bar) pairs produced in association with a photon in proton-proton collisions at root s = 8TeV is presented. The analysis uses data collected with the ...
Measurement of top quark polarisation in t-channel single top quark production
(Journal of High Energy Physics, 2016)
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 ...
Search for anomalous Wtb couplings and flavour-changing neutral currents in t-channel single top quark production in pp collisions at root s=7 and 8 TeV
(Journal of High Energy Physics, 2017)
Single top quark events produced in the t channel are used to set limits on anomalous Wtb couplings and to search for top quark flavour-changing neutral current (FCNC) interactions. The data taken with the CMS detector at ...
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
