Top quark properties measurements and searches at ATLAS and CMS / Wuchterl, Sebastian (CERN) /ATLAS and CMS Collaborations
Theoretical predictions for processes involving top quarks, such as top quark-antiquark pair production, depend on fundamental standard model (SM) parameters like the top quark mass or potentially receive contributions from beyond-the-SM (BSM) physics. By comparing predictions with measurements performed at the ATLAS and CMS experiments, SM parameters can be determined precisely, or measurements can be used as a powerful probe for BSM physics.

Higgs cross-section ( including di-Higgs ) with CMS and ATLAS / Lange, Torben (NICPB, Tallinn) /ATLAS and CMS Collaborations
Since the discovery of the Higgs boson in 2012 by the CMS and ATLAS collaborations a lot of progress has been made in verifying the nature of this new bosonic particle. Still, questions remain as to whether this new particle is the standard model (SM) Higgs boson, and whether it gives us hints of where physics beyond the SM (BSM) might be hidden. [...]

Heavy Neutrino Searches at Hadron Colliders / Vizan Garcia, Jesus Manuel (Cantabria Inst. of Phys.) /ATLAS and CMS Collaborations
A wide variety of searches for Heavy neutral leptons (HNLs) is carried out at the Large Hadron Collider, featuring a variety of signatures and theoretical models. In this note, several recent searches carried out by the CMS and ATLAS experiments for a HNL mass range from 1 GeV to several TeVs are reviewed..

Underlying-event studies with strange hadrons in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
Properties of the underlying-event in $pp$ interactions are investigated primarily via the strange hadrons $K_{S}^{0}$, $\Lambda$ and $\bar\Lambda$, as reconstructed using the ATLAS detector at the LHC in minimum-bias $pp$ collision data at $\sqrt{s} = 13$ TeV. [...]
