Effective field theory interpretations of the search for $HH\rightarrow b\bar{b}\gamma\gamma$ with 308 fb$^{-1}$ of data collected at $\sqrt{s} = 13$ TeV and 13.6 TeV with the ATLAS detector
This note presents interpretations of a search for Higgs boson pair production in the $b\bar{b}\gamma\gamma$ final state using the Standard Model Effective Field Theory (SMEFT) and Higgs Effective Field Theory (HEFT) frameworks. [...]

Electroweak and QCD Measurements in ATLAS / Fabbri, Laura (Universita e INFN, Bologna (IT)) /ATLAS Collaboration
This talk will discuss recent results from the ATLAS experiment concerning measurements in the electroweak and QCD sector. The highlighted topics include precision measurements of Drell-Yan and multiboson processes (including vector-boson-scattering), differential measurements of vector boson plus jets and multijets, novel study of jet substructures, probe of soft QCD phenomena, and precision heavy-flavor measurements. [...]

EFT measurements - ATLAS / Mazzeo, Elena (CERN) /ATLAS Collaboration
Effective field theories (EFTs) offer a powerful framework to search for new physics without relying on a specific UV-complete model. This talk presents recent ATLAS measurements reinterpreted in the EFT framework, with a focus on Higgs boson physics..

Higgs Measurements using Simulation Based Inference Techniques (ATLAS+CMS) / Park, Tae Hyoun (Max Planck Society (DE)) /ATLAS Collaboration
This presentation presents two analyses (one from ATLAS, one from CMS) performed using a novel inference technique, called Simulation-based inference, to perform parameter estimation using Higgs measurements..

Measurements and interpretation of the Higgs boson differential and production mode cross sections in the $H \rightarrow ZZ^* \rightarrow 4\ell$ channel at $\sqrt{s}=13.6$ TeV with the ATLAS detector
Higgs boson production cross-sections are measured in the $H\rightarrow~ZZ^\ast\rightarrow~4\ell$ decay channel based on 56 fb$^{-1}$ of proton-proton collision data produced at the Large Hadron Collider at a centre-of-mass energy of 13.6 TeV and recorded by the ATLAS detector in 2022 and 2023.

Exploring the CP-sensitive STXS staging in the H→WW* decay channel by the ATLAS experiment / Marr, Metea Castilleja (Simon Fraser University (CA)) ; Basso, Matthew Joseph (TRIUMF (CA)) /ATLAS Collaboration
The current STXS Stage 1.2 binning is not sensitive to the charge-parity properties of the Higgs boson. Parallel to the ongoing effort to finalize the STXS Stage 1.3 bins, the ATLAS experiment has studied the potential for measuring CP-sensitive STXS-like bins the $H\rightarrow WW^\ast$ decay channel.

Basis for anomalous quartic gauge couplings / Durieux, Gauthier (Louvain U., CP3) ; Remmen, Grant N. (New York U., CCPP) ; Rodd, Nicholas L. (LBL, Berkeley ; UC, Berkeley) ; Éboli, O.J.P.

In this note, we give a definitive basis for the dimension-eight operators leading to quartic - but no cubic - interactions among electroweak gauge bosons. These are often called anomalous quartic gauge couplings, or aQGCs. [...]

Higgs highlights at ATLAS / He, Yajun (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
In the past months, ATLAS has published many Higgs results. In this 15min talk, I will highlight the most high-profile results from the Higgs studies (including di-Higgs) in the past months..

Learning from radiation at a very high energy lepton collider / Chen, Siyu (EPFL, Lausanne, LPTP) ; Glioti, Alfredo (EPFL, Lausanne, LPTP) ; Rattazzi, Riccardo (EPFL, Lausanne, LPTP) ; Ricci, Lorenzo (EPFL, Lausanne, LPTP) ; Wulzer, Andrea (EPFL, Lausanne, LPTP ; Padua U., Astron. Dept.)
We study the potential of lepton collisions with about $10\text{ TeV}$ center of mass energy to probe Electroweak, Higgs and Top short-distance physics at the $100\text{ TeV}$ scale, pointing out the interplay with the long-distance ($100\text{ GeV}$) phenomenon of Electroweak radiation. On one hand, we find that sufficiently accurate theoretical predictions require the resummed inclusion of radiation effects, which we perform at the double logarithmic order. [...]
