Searches for new phenomena in final states with taus using the ATLAS detector
/ Carratta, Giuseppe (Universita e INFN, Bologna (IT))
/ATLAS Collaboration
Many theories beyond the Standard Model predict new phenomena, such as leptoquarks, vector like leptons, Z', W' bosons, KK gravitons, supersymmetry, new scalars or heavy leptons, in final states with isolated, high-pT taus. Searches for new physics with such signatures, produced either resonantly or non-resonantly, are performed using the ATLAS experiment at the LHC. [...]

Measurement of the Higgs coupling to top quarks with four-top-quark production
/ Roberts, Ryan (University of California Berkeley (US))
/ATLAS Collaboration
Measurement of the Higgs coupling to top quarks with four-top-quark production Nov 30, 2023, 12:15 PM 15m A214 (Main Building) Parallel session Precision & Yukawas Parallel: Precision & Yukawas Speaker Ryan ROBERTS Description Recent observation of four-top-quark production by ATLAS and CMS has opened a new channel for measurement of the top-Higgs Yukawa coupling yt as the four-top cross-section receives contributions from tree-level diagrams mediated by an off-shell Higgs boson. This measurement compliments constraints placed on yt from top-associated Higgs production and from resolving the loops in gluon-gluon fusion production and diphoton decays of the Higgs boson because the four-top measurement differs significantly in final state and in the modelling assumptions made about the Higgs.

Search with H->tautau
/ De Maria, Antonio (Nanjing University (CN))
/ATLAS Collaboration
Higgs boson decays into pairs of tau leptons provide a clean signature that can be used in searches for processes that have not yet been observed. This talk presents the results of such searches by the ATLAS experiment, using the full Run 2 pp collision dataset collected at 13 TeV..
