Binned angular analysis of $B^{0} \to K^{*0} \mu^{+} \mu^{-}$ with LHCb / Carus, Leon (Heidelberg U.)
The analysis of $b\to s\ell^+\ell^-$ flavor-changing neutral current decays is a powerful test of the Standard Model (SM). [...]

Search for CP violation in $ \mathrm{D^0}\to\mathrm{K^0_S}\mathrm{K^0_S} $ decays in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A search is reported for charge-parity CP violation in $ \mathrm{D^0}\to\mathrm{K^0_S}\mathrm{K^0_S} $ decays, using data collected in proton-proton collisions at $ \sqrt{s} = $ 13 TeV recorded by the CMS experiment in 2018. [...]

$b \to c l \bar{\nu}$ decays at LHCb / Chen, Chen (Marseille, CPPM)
This report introduces two recent measurements of semileptonic $b$-hadron decays at the LHCb experiment, including a test of Lepton Flavour Universality (LFU) using $\bar{B}^0 \to D^{(*)+} l^- \bar{\nu}_l$ decays where $l\in\{\mu,\tau\}$, and a study of the $D^{*+}$ longitudinal polarisation in the $\bar{B}^0 \to D^{*+} \tau^- \bar{\nu}_\tau$ decay.

Updates on inclusive charmed and bottomed meson decays from the lattice / Kellermann, Ryan (KEK, Tsukuba) ; Barone, Alessandro (U. Mainz, PRISMA ; U. Southampton (main)) ; Hashimoto, Shoji (KEK, Tsukuba) ; Jüttner, Andreas (U. Southampton (main) ; CERN) ; Kaneko, Takashi (KEK, Tsukuba ; KMI, Nagoya)
With the development of lattice QCD in recent years, a determination of decay rates for inclusive semileptonic decays from lattice correlators now seems viable. [...]

Search for Vector-like Quark, Heavy Neutral Lepton and Long-lived Particles at ATLAS and CMS / Grancagnolo, Sergio (INFN, Lecce)
Several theories beyond the Standard Model (BSM) predict heavy neutral leptons, or long-lived particles with unique signatures which are difficult to reconstruct. [...]
