Search for associated production of a Z boson with a single top quark and for tZ flavour-changing interactions in pp collisions at s√=8 TeV
(Springer International Publishing, 2017-07-03)
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 ...
Measurement of the tt¯ production cross section using events with one lepton and at least one jet in pp collisions at √s=13 TeV
(Springer International Publishing, 2017-09-13)
A measurement of the tt¯tt¯ production cross section at s√=13s=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. ...
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
(Springer International, 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 CP violation in t(t)over-bar production and decay in proton-proton collisions at root s=8 TeV
(Springer International, 2017)
The results of a first search for CP violation in the production and decay of top quark-antiquark ( tt¯tt¯ ) pairs are presented. The search is based on asymmetries in T-odd, triple-product correlation observables, where ...
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 ...
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 ...
Search for top quark decays via Higgs-boson-mediated flavor-changing neutral currents in pp collisions at root √s = 8 TeV
(Springer International Publishing, 2017-02-15)
A search is performed for Higgs-boson-mediated flavor-changing neutral currents in the decays of top quarks. The search is based on proton-proton collision data corresponding to an integrated luminosity of 19.7 fb(-1) at ...
