Rare and exotic Higgs decays in ATLAS / Boye, Diallo (Brookhaven National Laboratory (US)) /ATLAS Collaboration
The discovery of the Higgs boson in 2012 marked a major milestone in particle physics, completing the Standard Model (SM). However, rare and exotic decays of the Higgs boson offer unique opportunities to explore physics beyond the Standard Model (BSM). [...]

Search for hadronic decays of feebly-interacting particles at NA62 / Cortina Gil, E.
The NA62 experiment at CERN has the capability to collect data in a beam-dump mode, where 400 GeV protons are dumped on an absorber. In this configuration, New Physics particles, including dark photons, dark scalars, and axion-like particles, may be produced in the absorber and decay in the instrumented volume beginning approximately 80 m downstream of the dump. [...]

Search for Higgs boson decays into a $Z$ boson and a light hadronically decaying resonance in 140 fb$^{-1}$ of 13 TeV $pp$ collisions with the ATLAS detector / ATLAS Collaboration
A search for decays of the Higgs boson into a $Z$ boson and a light resonance, with a mass of 0.5-3.5 GeV, is performed using the full 140 fb$^{-1}$ dataset of 13 TeV proton-proton collisions recorded by the ATLAS detector during Run 2 of the LHC. [...]

Studies of Axion-Like Particle Searches with the ATLAS Forward Proton (AFP) Detector for Run-3 and HL-LHC / Sakova, Haritina
This summer student project investigates the potential sensitivity increase of Axion-Like Particle (ALP) detection at the Large Hadron Collider (LHC) from Run-2 to Run-3 and to the High Luminosity LHC (HL-LHC). [...]

Search for leptonic decays of dark photons at NA62Search for Leptonic Decays of Dark Photons at NA62 / NA62 Collaboration
The NA62 experiment at CERN, configured in beam-dump mode, has searched for dark photon decays in flight to electron-positron pairs using a sample of $1.4 \times 10^{17}$ protons on dump collected in 2021. No evidence for a dark photon signal is observed. [...]

Chasing the axion-like particles using the proton tagging with the CMS experiment / Hrynchak, Ivan (Taras Shevchenko National University of Kyiv)
Various theories beyond the SM predict axion-like particles (ALPs) to address the longstanding questions in particle physics: the strong CP problem and the nature of dark matter. [...]

Ultra narrowband detection scheme for dark photon / axion around 30 GHz / Miyazaki, A (Uppsala U.) ; Lofnes, T (Uppsala U.) ; Caspers, F (ESI, Archamps ; CERN) ; Spagnolo, P (INFN, Pisa) ; Jelonnek, J (KIT, Karlsruhe) ; Ruess, T (KIT, Karlsruhe) ; Steinmann, J L (KIT, Karlsruhe) ; Thumm, M (KIT, Karlsruhe)
We demonstrated that ultra narrowband filtering at 30 GHz dramatically enhances the signal-to-noise ratio to search for dark matter candidates which couple to millimeter waves. [...]

Overview of ATLAS forward proton detectors: status, performance and new physics results / Lewicki, Maciej Piotr (Polish Academy of Sciences (PL)) /ATLAS Collaboration
A key focus of the physics program at the LHC is the study of head-on proton-proton collisions. However, an important class of physics can be studied for cases where the protons narrowly miss one another and remain intact. [...]

Light Diphoton Resonances / Meyer, Chris (Indiana University (US)) /ATLAS Collaboration
New light resonances are a generic signature of models of new phenomena beyond the Standard Model. The diphoton final states provides a clean final state and provides sensitivity to a wide class of such signals, in particular axion-like particles (ALPs). [...]
