The results of the most recent measurements of the inclusive $\mathrm{t\bar{t}}$ cross section performed by the ATLAS and CMS experiments at the CERN LHC are summarized. These include results obtained in proton-proton collisions at different centre-of-mass energies, and the first observation of $\mathrm{t\bar{t}}$ production in proton-lead collisions. [...]

Recent single top measurements with ATLAS and CMS
XVII International Workshop on Deep Inelastic Scattering, DIS2019, TorinoTorino, Italy, 8 Apr 2019 - 12 Apr 20192019-04-082019-04-12
Latest results on inclusive top quark pair and single top quark production cross sections are presented using proton-proton collision data collected by CMS. The single top quark analyses investigate separately the production of top quarks via t-channel exchange, in association with a W boson (tW) or via the s-channel. [...]

Rare top quark production at the LHC: Results on $\mathrm{t\bar{t}Z, t\bar{t}W, t\bar{t}\gamma, tZ, t\gamma}$, and $\mathrm{t\bar{t}t\bar{t}}$ with the ATLAS and CMS experiments
XVII International Workshop on Deep Inelastic Scattering, DIS2019, TorinoTorino, Italy, 8 Apr 2019 - 12 Apr 20192019-04-082019-04-12
A comprehensive set of measurements of top quark pair and single top quark production in association with EWK bosons (W, Z or ɣ) is presented. The results are compared to theory predictions and re-interpreted as searches for new physics inducing deviations from the standard model predictions using an effective field theory approach. [...]

Combinations of single-top-quark production cross-section measurements and $|f_{\rm LV}V_{tb}|$ determinations at $\sqrt{s}=7$ and 8 TeV with the ATLAS and CMS experiments
[arXiv:1902.07158; CERN-EP-2019-005]
 GO
This paper presents the combinations of single-top-quark production cross-section measurements by the ATLAS and CMS Collaborations, using data from LHC proton-proton collisions at $\sqrt{s}=7$ and 8 TeV corresponding to integrated luminosities of 1.17 to 5.1 fb$^{-1}$ at $\sqrt{s}=7$ TeV, and 12.2 to 20.3 fb$^{-1}$ at $\sqrt{s}=8$ TeV. These combinations are performed per centre-of-mass energy and for each production mode: $t$-channel, $tW$, and $s$-channel. [...]

Probing the photonic content of the proton using photon-induced dilepton production in $p+\textrm{Pb}$ collisions at the LHC
[arXiv:1901.06305; DESY-19-010]
 GO
We propose a new experimental method to probe the photon parton distribution function inside the proton (photon PDF) at LHC energies. The method is based on the measurement of dilepton production from the $\gamma p\rightarrow\ell^+\ell^-+X$ reaction in proton--lead collisions. [...]
