Inclusive and differential cross-section measurements in the single top tW e-mu channel with CMS at Run 3 (YSF) / Soto Rodriguez, Alejandro (Oviedo U.) /CMS Collaboration
The first measurements of the inclusive and normalised differential cross sections for the production of single top quarks in association with a W boson in proton-proton collisions at a centre-of-mass energy of 13.6 TeV are presented. The data used were recorded with the CMS detector at the LHC during 2022, and correspond to an integrated luminosity of 34.7 $\mathrm{fb}^{-1}$. [...]

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..

Search for time-dependent $CP$ violation in $D^0\to \pi^+\pi^-\pi^0$ decays
A measurement of time-dependent $CP$ violation in $D^0 \rightarrow \pi^+ \pi^- \pi^0$ decays using a $pp$ collision data sample collected by the LHCb experiment in 2012 and from 2015 to 2018, corresponding to an integrated luminosity of 7.7$\,\mathrm{fb}^{-1}$, is presented. [...]
