Measurement of the four-lepton invariant mass spectrum in 13 TeV proton-proton collisions with the ATLAS detector
[arXiv:1902.05892; CERN-EP-2018-318]
A measurement of the four-lepton invariant mass spectrum is made with the ATLAS detector, using an integrated luminosity of 36.1 fb$^{−1}$ of proton-proton collisions at $ \sqrt{s} $ = 13 TeV delivered by the Large Hadron Collider. The differential cross-section is measured for events containing two same-flavour opposite-sign lepton pairs. [...]

Search for pair production of Higgs bosons in the $b\bar{b}b\bar{b}$ final state using proton-proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector
[CERN-EP-2018-029; arXiv:1804.06174]
A search for Higgs boson pair production in the $ b\overline{b}b\overline{b} $ final state is carried out with up to 36.1 fb$^{−1}$ of LHC proton-proton collision data collected at $ \sqrt{s}=13 $ TeV with the ATLAS detector in 2015 and 2016. Three benchmark signals are studied: a spin-2 graviton decaying into a Higgs boson pair, a scalar resonance decaying into a Higgs boson pair, and Standard Model non-resonant Higgs boson pair production. [...]

Search for light resonances decaying to boosted quark pairs and produced in association with a photon or a jet in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
[arXiv:1801.08769; CERN-EP-2017-280]
This Letter presents a search for new light resonances decaying to pairs of quarks and produced in association with a high-$p_T$ photon or jet. The dataset consists of proton–proton collisions with an integrated luminosity of 36.1 fb$^{−1}$ at a centre-of-mass energy of $\sqrt{s}=13$ TeV recorded by the ATLAS detector at the Large Hadron Collider.

Search for scalar resonances decaying into $\mu^+\mu^-$ in events with and without $b$-tagged jets produced in proton-proton collisions at $\sqrt{s} =$ 13 TeV with the ATLAS detector
[arXiv:1901.08144; CERN-EP-2018-300]
A search for a narrow scalar resonance decaying into an opposite-sign muon pair produced in events with and without b-tagged jets is presented in this paper. The search uses 36.1 fb$^{−1}$ of $\sqrt{s} =$ 13 TeV proton-proton collision data recorded by the ATLAS experiment at the LHC. [...]

Probing the photonic content of the proton using photon-induced dilepton production in p+Pb collisions at the LHC
[arXiv:1901.06305; DESY-19-010]
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 $γp → ℓ^+ ℓ^- + X$ reaction in proton-lead collisions. [...]

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]
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 QCD using top quark pair production at $\sqrt{s} =$ 13 TeV in CMS
European Physical Society Conference on High Energy Physics, EPS-HEP2019, GhentGhent, Belgium, 10 Jul 2019 - 17 Jul 20192019-07-102019-07-17  GO
A measurement of the inclusive top quark-antiquark pair production cross section in proton proton collisions at a centre-of-mass energy of 13 TeV is used by the CMS experiment, together with the theoretical prediction at next-to-next-to-leading order, to determine the top quark mass and to extract a value of the strong coupling constant with different sets of parton distribution functions. Dilepton events are selected and the cross section is measured from a likelihood fit to the final state distributions. [...]
