Rare top quark production at the LHC: t¯tZ, t¯tW, t¯tγ, tZq, tγq, and t¯tt¯t
/ Knolle, Joscha (DESY)
/ATLAS Collaborations ; CMS Collaborations
A comprehensive set of measurements of top quark pair and single top quark production in association with electroweak bosons (W, Z, or γ) is presented. The results are compared to standard model (SM) predictions and used to set limits on new physics effects that would induce deviations from the SM. [...]

Latest measurements in single top quark with the CMS experiment
/ Iemmi, Fabio (INFN, Bologna ; Bologna U.)
/CMS
The latest measurements obtained by the CMS Collaboration in single top quark production are summarized. We present both inclusive and differential cross section measurements in different production modes, which lead to constraints on proton parton distribution functions (PDFs) and measurements of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |Vtb| and top quark spin asymmetry Aℓ; we also show searches for rare Standard Model (SM) processes, such as the first observation of tZq associated production and the first evidence for tγq associated production..

Studies of tt+V at CMS
/ Khvastunov, Illia (Gent U.)
/CMS Collaboration
A measurement of the production cross-section of a pair of top quarks in association with a photon, using 19.7 fb−1 of pp collision data collected by CMS detector at √s= 8 TeV, and with W and Z boson, using 12.9 fb−1 of data collected at √s= 13 TeV, is presented. The measurement of t¯tγ is performed in in the fiducial phase space corresponding to the semileptonic decay chain of the top quark pair, and the cross section is measured relative to the inclusive top quark pair production cross section.

Top quark production cross sections and rare processes at CMS and ATLAS
/ Saggio, Alessia (DESY)
/ATLAS and CMS Collaborations
Inclusive and differential measurements of cross sections as well as searches for rare processes in the top quark sector provide an important test of the standard model (SM) and a powerful probe of physics beyond the SM (BSM).
Recent results on inclusive and differential measurements of t¯t, tZq, and t¯t+X processes are reported, together with searches for
flavour changing neutral currents (FCNCs) and charged lepton flavour violation (CLFV) in top quark processes, and for production of four top quarks.
All results are obtained in proton-proton collision data, recorded by the ATLAS and CMS experiments at the CERN LHC from 2015 to 2018
at √s=13~TeV.}
