The use of AI to improve the sensitivity for HF and dark sector at ATLAS and CMS / Herwig, Christian (University of Michigan (US)) /ATLAS Collaboration
The data collected by ATLAS and CMS during the recent Runs 2 and 3 offer a unique potential to probe the physics of heavy flavor and potential Dark Sectors. However, realizing this potential presents a major experimental challenge, as the intense environment of energetic proton-proton collisions can easily obscure the subtle targets of these measurements.

Dark Sector: LHC Experimental Status / Liu, Bingxuan (Sun Yat-Sen University (CN)) /ATLAS Collaboration
Dark sector has increasing attention from both the theory and experiment communities. In this talk, a few topics are selected to discuss the complementarity between different experiments, including CMS/ATLAS/LHCb and forward/beam-dump experiments, using the dark photon search as an example. [...]

The forward physics facility : physics opportunities and conceptual design / FPF Collaboration
The Forward Physics Facility (FPF) is a proposed extension of the HL-LHC program designed to exploit the unique scientific opportunities offered by the intense flux of high energy neutrinos, and possibly new particles, in the far-forward direction. Located in a well-shielded cavern 627 m downstream of one of the LHC interaction points, the facility will support a broad and ambitious physics program that significantly expands the discovery potential of the HL-LHC.

ATLAS Searches for Supersymmetry and BSM Higgs / Sawada, Ryu (University of Tokyo (JP)) /ATLAS Collaboration
Supersymmetry and additional Higgs bosons are highly motivated to solve problems in the Standard Model. The ATLAS experiment at the LHC has been searching for hints of them, using many signatures to cover parameter spaces of various Beyond the Standard Model (BSM) models. [...]

Results for prompt dark sector mediators from ATLAS / Franchellucci, Stefano (U. Geneva (main))
The presence of a non-baryonic Dark Matter (DM) component in the Universe is motivated from the observation of its gravitational interaction. [...]

Search for new physics in final states with semi-visible jets or anomalous signatures using the ATLAS detector / Park, Ki Ryeong (Columbia University (US)) /ATLAS Collaboration
A search is presented for hadronic signatures of beyond the Standard Model (BSM) physics, with an emphasis on signatures of a strongly-coupled hidden dark sector accessed via resonant production of a Z' mediator using 140fb-1 of Run-2 pp collision data at 13 TeV. The Z' mediator is considered to decay to two dark quarks, each of which then hadronizes and decays to showers containing both dark and Standard Model particles, producing a topology of interacting and non-interacting particles within a jet known as "semi-visible". [...]

Results for prompt dark sector mediators from ATLAS / Franchellucci, Stefano (Universite de Geneve (CH)) /ATLAS Collaboration
The presence of a non-baryonic Dark Matter (DM) component in the Universe is inferred from the observation of its gravitational interaction. If Dark Matter interacts weakly with the Standard Model (SM) it could be produced at the LHC. [...]

Search for new physics in final states with semivisible jets or anomalous signatures using the ATLAS detector / ATLAS Collaboration
A search is presented for hadronic signatures of beyond the Standard Model (BSM) physics, with an emphasis on signatures of a strongly-coupled hidden dark sector accessed via resonant production of a $Z'$ mediator. The ATLAS experiment dataset collected at the Large Hadron Collider from 2015 to 2018 is used, consisting of proton-proton collisions at $\sqrt{s}$ = 13 TeV and corresponding to an integrated luminosity of 140 fb$^{-1}$.

Searches for hidden sectors using $K^+\to\pi^+X$ decays / Cortina Gil, Eduardo (Louvain U., CP3) ; Jerhot, Jan (Louvain U., CP3 ; Munich, Max Planck Inst.) ; Minucci, Elisa (Louvain U., CP3 ; Frascati) ; Padolski, Sergey (Louvain U., CP3) ; Petrov, Plamen (Louvain U., CP3) ; Shaikhiev, Artur (Louvain U., CP3 ; Lancaster U.) ; Volpe, Roberta (Louvain U., CP3 ; INFN, Perugia) ; Numao, Toshio (TRIUMF) ; Petrov, Yevgeniy (TRIUMF) ; Shang, Victor (TRIUMF) et al.
Results from the study of the rare decays $K^+\to\pi^+\nu\bar{\nu}$, $K^{+}\to \pi^{+}\mu^{+}\mu^{-}$ and $K^{+}\to\pi^{+}\gamma\gamma$ at the NA62 experiment at CERN are interpreted in terms of improved limits for $B(K^+\to\pi^+X)$ and coupling parameters of hidden-sector models, where X is a mediator. World-leading limits are achieved for dark photon, dark scalar and axion-like particle models..
