Measurements of top quark asymmetries / Faltermann, Nils (KIT, Karlsruhe, EKP) /ATLAS and CMS Collaborations
The study of top quark asymmetries at the LHC provides an excellent opportunity to probe subtle differences in the production of top quarks and antiquarks made by the standard model of particle physics. In this contribution, the latest experimental results on this topic by the ATLAS and CMS Collaborations are summarized..

Enhancing CMS Passive Material Modeling in Track Reconstruction Using ACTS / Damenti, Lorenzo (INFN, Florence ; Florence U.) /CMS Collaboration
The tracker passive material cannot be neglected within the charged particle track reconstruction algorithm. In particular, track propagation must account for material effects such as multiple scattering and energy loss. [...]

Measurement of $ {\mathrm{B}} $ meson production fraction ratios in proton-proton collisions at $ \sqrt{s} = $ 13 TeV using open-charm and charmonium decays
Production fraction ratios of $ {\mathrm{B}^{+}} $, $ {\mathrm{B}^0} $, and $ \mathrm{B}_{s}^{0} $ mesons are measured in proton-proton collisions at $ \sqrt{s} = $ 13 TeV using a special data set recorded in 2018 with high-rate triggers designed to collect an unbiased sample of $ 10^{10} \mathrm{b} $ hadrons with the CMS experiment at the LHC\@.

Dark Matter from Eternity / Franciolini, G. (U. Padua (main) ; INFN, Padua ; CERN) ; Peloso, M. (U. Padua (main) ; INFN, Padua) ; Riotto, A. (U. Geneva (main))
We propose that the totality of dark matter in the universe might ascribe its origin to one of the key properties of cosmological inflation, that it may be eternal: regions that at the end of the primordial accelerated expansion of the universe never reheated, but keep eternally inflating, manifest themselves as primordial black holes in our observable universe.

Top physics in ATLAS and CMS / Burgard, Carsten (Hamburg U.) /ATLAS and CMS Collaborations
Top-quark physics at the Large Hadron Collider has entered a precision era, enabled by the full Run 2 data set and the first results from Run 3. The large production cross section of top quarks allows for a diverse experimental program ranging from precision measurements of Standard Model parameters to searches for rare processes and indirect probes of physics beyond the Standard Model.

Optimization and Outer Tracker Extension of the Cellular Automaton Algorithm for CMS Phase-2 HLT Tracking / Jan Gerrit Schulz /CMS Collaboration
The Phase-2 Upgrade for the CMS experiment at the High-Luminosity Large Hadron Collider introduces new and improved detectors, including a new tracker. It will enable higher-quality track reconstruction in the pixel detector, particularly in the forward region (pseudorapidity $\lvert\eta\rvert > 3$), by recording hits in many more layers than is currently possible.
