"Searches for Beyond Standard Model Higgs boson decays (including low mass resonances)" at EPS-HEP2025 / Hofer, Judith (Univ. of Valencia and CSIC (ES)) /ATLAS Collaboration
The discovery of the Higgs boson with the mass of about 125 GeV completed the particle content predicted by the Standard Model. Even though this model is well established and consistent with many measurements, it is not capable of explaining some observations by itself. [...]

Searches for new phenomena in leptonic final states using the ATLAS detector / Wielers, Monika (Science and Technology Facilities Council STFC (GB)) /ATLAS Collaboration
Many theories beyond the Standard Model predict new phenomena, such as Z', W' bosons, KK gravitons, vector-like leptons or heavy leptons, in final states with isolated, high-pT leptons (e/mu/tau) or photons. Searches for new physics with such signatures, produced either resonantly or non-resonantly, are performed using the ATLAS experiment at the LHC.. [...]

Measuring photon-induced tau-lepton pair production with ATLAS / Beresford, Lydia Audrey (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
This talk presents ATLAS differential cross-section measurements of $\tau$-lepton pair production in ultra-peripheral Pb+Pb collisions. The 2015 and 2018 Pb+Pb datasets are utilised and correspond to 1.93 $nb^{-1}$ recorded at $\sqrt{s_{NN}}$= 5.02 TeV..

Searches for unusual signatures in leptonic and missing energy channels with the ATLAS detector / Woodward, Eleanor Luise (Columbia University (US)) /ATLAS Collaboration
Various theories beyond the Standard Model predict new, long-lived particles with unique signatures involving leptons or missing energy, which are difficult to reconstruct and for which estimating the background rates is also a challenge. These include displaced have neutral leptons, SUSY models involving displaced electron/muon pairs, heavy charged particles, and displaced vertices. [...]

Measurements of rare electroweak processes including vector boson scattering and tri-boson production with ATLAS / Kostyukhin, Vadim (Universitaet Siegen (DE)) /ATLAS Collaboration
Measurements of rare processes in the electroweak sector provide unprecedented constraints of the SM theory, and unique sensitivity to study the electroweak symmetry breaking (VBS processes) and the quartic boson self-couplings (VBS and triboson processes). In addition to cross-section measurements, studies of boson polarization states in VBS processes are being actively pursued to bring further sensitivity to new phenomena. [...]

The ATLAS trigger system / De Maria, Antonio (Nanjing University (CN)) /ATLAS Collaboration
The ATLAS experiment in the LHC Run 3 uses a two-level trigger system to select events of interest to reduce the 40 MHz bunch crossing rate to a recorded rate of up to 3 kHz of fully-built physics events. The trigger system is composed of a hardware based Level-1 trigger and a software based High Level Trigger. [...]

Estimation of backgrounds from jets misidentified as tau leptons using the Universal Fake Factor method with the ATLAS detector / Morodei, Federico (Sapienza Universita e INFN, Roma I (IT)) /ATLAS Collaboration
Physical processes with one or more τ-lepton in the final state play an important role in several analyses of the ATLAS experiment physics program. The usage of hadronic channels, in which τ-leptons decay into one or more pions, enables to exploit the large statistics associated with hadronic τ-lepton decays, but also requires a precise estimate of a sizable background of hadronic jets mis-reconstructed as fake τ-leptons.

Measurement of multi-jets and boson plus jets production with ATLAS / Delagrange, Line (Centre National de la Recherche Scientifique (FR)) /ATLAS Collaboration
Production of multiple jets or bosons plus jets at the LHC offers an unprecedented opportunity to study QCD in the high-energy regime. As experimental precision advances, thorough QCD studies are enabled by measurements of a variety of different observables, including different topological configurations between vector bosons and jets, jet substructure observables, and heavy-flavor jets.

Measurement and related interpretations of $W^{\pm}Z$ cross-sections in pp collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector / Boudet, Leo (Centre National de la Recherche Scientifique (FR)) /ATLAS Collaboration
Measurements of integrated and differential cross-sections for $W^{\pm}Z$ production in proton–proton collisions are presented. The data collected by the ATLAS detector at the Large Hadron Collider from 2015 to 2018 at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV are used, corresponding to an integrated luminosity of 140 fb$^{-1}$.

Search for CP violating effects in HWW vertex in the WH production channel in 13 TeV pp collisions with the ATLAS detector / Kholodenko, Marina (Laboratory of Instrumentation and Experimental Particle Physics (PT)) /ATLAS Collaboration
The Standard Model (SM) predicts the Higgs boson to be a CP-even (scalar) particle. Any deviation from a purely CP-even interaction of the Higgs boson with other SM particles would indicate physics beyond the SM. [...]
