Measurements of inclusive and differential cross sections for top quark production in association with a Z boson in proton-proton collisions at $ \sqrt{s}= $ 13 TeV
Measurements are presented of inclusive and differential cross sections for Z boson associated production of top quark pairs ($ {\mathrm{t}\overline{\mathrm{t}}} \mathrm{Z} $) and single top quarks ($ \mathrm{t}\mathrm{Z}\mathrm{q} $ or $ \mathrm{t}\mathrm{W}\mathrm{Z} $). [...]

Measurement of the CKM angle $\gamma$ in $B^\pm\to DK(892)^{*\pm}$ decays / LHCb Collaboration
Measurements of $CP$ observables and the CKM angle $\gamma$ are performed in $B^{\pm} \to D K^*(892)^{\pm}$ decays, where $D$ represents a superposition of $D^0$ and $\overline{D}{}^0$ states, using the LHCb dataset collected during Run 1 (2011-2012) and Run 2 (2015-2018). [...]

Measurements of $WH$ and $ZH$ production with Higgs boson decays into bottom quarks and direct constraints on the charm Yukawa coupling in $13\,\mathrm{TeV}$ $pp$ collisions with the ATLAS detector
A study of the Higgs boson decaying into bottom quarks ($H \to b\bar{b}$) and charm quarks ($H \to c\bar{c}$) is performed, in the associated production channel of the Higgs boson with a $W$ or $Z$ boson, using $140\,\mathrm{fb}^{-1}$ of proton-proton collision data at $\sqrt{s} = 13\,\mathrm{TeV}$ collected by the ATLAS detector.

Non-resonant Di-Higgs searches with the CMS experiment / Dutta, Irene (Fermilab) /CMS Collaboration
The measurement of the production of Higgs boson pairs (HH) at the LHC allows the exploration of the Higgs boson interaction with itself, which is a fundamental test of the Standard Model theory. The most recent results from the CMS collaboration on measurements of non-resonant HH production using different final states and their combination using the data set collected by the CMS experiment at a centre of mass energy of 13 TeV will be presented here..

b-hive: a modern start-to-finish flavor tagging framework / Philipp Alexander Jung /CMS Collaboration
Deep-learning-based algorithms have become essential for a large fraction of tasks in high-energy-physics (HEP) research, like the identification of jets originating from heavy quarks at the Compact Muon Solenoid (CMS) Experiment at the Large Hadron Collider (LHC) at CERN. Existing frameworks are often limited in capability and based on older software libraries by today's industry standards.With our newly developed framework b-hive, we aim to build a full package capable of handling a flavor tagging model with modern tools.
