Standard Model multibosons at ATLAS and CMS (proceeding) / Giannini, Antonio (University of Science and Technology of China (CN))
Multibosons production processes at the LHC provide stringent tests of the electroweak sector of the Standard Model (SM), with direct sensitivity to gauge boson self-interactions and possible new physics effects. [...]

Searches for Quantum Black Holes with the ATLAS detector / Hasan, Rosanne Zara (University of London (GB))
This proceedings presents a search for quantum black holes in electron+jet and muon+jet final states using a partial ATLAS Run~3 dataset of $pp$ collisions at $\sqrt{s}=13.6~\textrm{TeV}$ recorded at the Large Hadron Collider \cite{ATLAS:2026hzb}, corresponding to an integrated luminosity of $164~\mathrm{fb}^{-1}$. [...]

Deep Sets and event-level maximum-likelihood estimation for fast pile-up jet rejection at the ATLAS High Level Trigger
Multiple proton-proton interactions occur in the same bunch crossing at the LHC (“pile-up”), with the mean number of interactions per bunch crossing reaching up to about 60 in Run 3 and up to about 200 at the High-Luminosity LHC. [...]

Searches for vector-like quarks and leptoquarks at ATLAS and CMS / Grancagnolo, Sergio (INFN Lecce e Universita del Salento (IT))
Most recent results from the ATLAS and CMS experiments are presented: using about 140 fb$^{-1}$ of $pp$ collisions data at 13 TeV, collected during the LHC Run 2, searches of leptoquarks and vector-like quarks are performed, in various production modes and decay channels..

New results from test-beam performance studies of 3D triplet modules for the ATLAS ITk detector / Ravera, Simone (INFN e Universita Genova (IT))
For the High Luminosity upgrade of the Large Hadron Collider (HL-LHC), the ATLAS Inner Detector will be replaced by the all-silicon Inner Tracker (ITk), designed to operate in a significantly more challenging radiation environment and at higher collision rates. [...]
