Measurement of the high-mass tau-tau production cross-section and constraints on Leptoquarks, Z' bosons, and effective couplings / Koch, Simon Florian (University of Oxford (GB)) /ATLAS Collaboration
The production of high-mass 𝜏-lepton pairs constitutes a very effective process to probe the Standard Model flavour sector and to search for new physics. The first measurement of the high-mass $\tau \bar{\tau}$ production cross section is presented, performed by the ATLAS Collaboration with the dataset of 140 fb-1 of pp collisions at $\sqrt{s} = 13$~TeV.

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.

Search for rare processes and lepton-flavor-violating decays of Higgs boson at the ATLAS experiment / Zakareishvili, Tamar (Univ. of Valencia and CSIC (ES)) /ATLAS Collaboration
The Standard Model predicts several rare Higgs boson processes, including decays into a Z boson and a photon, a low-mass lepton pair and a photon, or a meson and a photon. Observing these rare decays would offer new and complementary insights into the Higgs boson's coupling structure beyond the more commonly studied channels. [...]

Prospects for Higgs Boson Research at the LHC / Sopczak, Andre (Czech Technical University in Prague (CZ))
The search for Higgs bosons in the Standard Model (SM) of particle physics and Beyond the Standard Model (BSM) started intensively at the Large-Electron-Positron (LEP) collider, which operated from 1989 to 2000, and later at the Tevatron from 2001 to 2011. [...]

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. [...]

Rare few-body decays of the Standard Model Higgs boson / d'Enterria, David (CERN) ; Le, Van Dung (Ho Chi Minh City U.)
We present a survey of rare and exclusive few-body decays of the standard model (SM) Higgs boson, defined as those into two to four final particles with branching fractions $\mathcal{B}\lesssim 10^{-5}$. Studies of such decays can be exploited to constrain Yukawa couplings of quarks and leptons, probe flavour-changing Higgs decays, estimate backgrounds for exotic Higgs decays into beyond-SM particles, and/or confirm quantum chromodynamics factorization with small nonperturbative corrections [...]
