Abstract The Standard Model of particles and fields describes the fundamental particles and
their interactions to high level of precision. The SM is nevertheless considered to be a low …

The observation of the production of four top quarks in proton-proton collisions is reported,
based on a data sample collected by the CMS experiment at a center-of-mass energy of 13 …

A bstract We study the phenomenology of a strongly-interacting top quark at future hadron
and lepton colliders, showing that the characteristic four-top contact operators give rise to …

The standard model (SM) production of four top quarks (tttt tt¯ tt¯) in proton–proton collisions
is studied by the CMS Collaboration. The data sample, collected during the 2016–2018 data …

A search for a heavy neutral lepton N of Majorana nature decaying into a W boson and a
charged lepton is performed using the CMS detector at the LHC. The targeted signature …

A bstract Measurements of both the inclusive and differential production cross sections of a
top-quark-top-antiquark pair in association with a Z boson (\(t\overline {t} Z\)) are presented …

A bstract A search for new phenomena in events with two same-charge leptons or three
leptons and jets identified as originating from b-quarks in a data sample of 36.1 fb− 1 of pp …

A bstract A measurement is performed of the cross section of top quark pair production in
association with a W or Z boson using proton-proton collisions at a center-of-mass energy of …

The production of four top quarks (tt¯ tt¯) is studied with LHC proton-proton collision data
samples collected by the CMS experiment at a center-of-mass energy of 13 TeV, and …

A combination of the results of several searches for the electroweak production of the
supersymmetric partners of standard model bosons, and of charged leptons, is presented …
