LFV and related rare decays at ATLAS and CMS / Huwiler, Marc (Zurich U.) /ATLAS and CMS Collaborations
Charged Lepton Flavour Conservation and Lepton Flavour Universality are observed symmetries of the Standard Model (SM) of particle physics, with no underlying theoretical principle enforcing them. Lepton Flavour Violation (LFV) is observed in the neutrino sector, through the spontaneous oscillation of neutrinos between the three flavour families. [...]

Prompt searches for feebly interacting particles at the LHC / Knolle, Joscha (Gent U.) /ATLAS and CMS Collaborations
Recent results from the ATLAS and CMS experiments in searches for prompt signatures of feebly interacting particles are presented. All presented results are based on the $2015{-}2018$ data set of $13\,\mathrm{TeV}$ proton-proton collisions, corresponding to an integrated luminosity of about $140\,\mathrm{fb}^{-1}$. [...]

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 / ATLAS Collaboration
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.

Multiboson results at ATLAS and CMS / Bhattacharya, Saptaparna (Wayne State U.) /ATLAS and CMS Collaborations
The study of multiboson processes at the Large Hadron Collider provides important tests of the non-Abelian gauge structure of the Standard Model of Particle Physics (SM). While processes featuring the scattering of vector bosons have been observed with early Run 2 data, the entirety of the Run 2 data allows for differential measurements of these processes further enabling precision tests of the SM.

Search for a new scalar decaying into new spin-1 bosons in four-lepton final states with the ATLAS detector / ATLAS Collaboration
A search is conducted for a new scalar boson $S$, with a mass distinct from that of the Higgs boson, decaying into four leptons ($\ell =$ $e$, $\mu$) via an intermediate state containing two on-shell, promptly decaying new spin-1 bosons $Z_\text{d}$: $S \rightarrow Z_\text{d}Z_\text{d} \rightarrow 4\ell$, where the $Z_\text{d}$ boson has a mass between 15 and 300 GeV, and the $S$ boson has a mass between either 30 and 115 GeV or 130 and 800 GeV.

ATLAS and CMS Higgs boson related measurements / Le Bihan, Anne-Catherine (Strasbourg, IPHC) /ATLAS and CMS Collaborations
Since its discovery in 2012, ATLAS and CMS Collaborations are constantly updating the Higgs boson properties and interaction measurements to characterize as precisely as possible the electroweak symmetry breaking mechanism. These proceedings report on the status of these measurements at the beginning of Summer 2024. [...]

Exploring jets substructure and flavour tagging in CMS and ATLAS / Malara, Andrea (Brussels U.) /ATLAS and CMS Collaborations
The identification and characterization of jets are crucial tasks for effectively probing fundamental particle interactions. The ATLAS and CMS experiments have developed cutting-edge techniques to improve jet identification and calibration, employing innovative approaches including advanced neural network architectures, attention-based mechanisms, and adversarial training.
