Search for Higgs boson pair production in the $b\bar{b}\gamma\gamma$ final state from 13 TeV $pp$ collision data with the ATLAS detector / Mazzeo, Elena (Università degli Studi e INFN Milano (IT)) /ATLAS Collaboration
A search for di-Higgs boson production in the bbγγ final state is presented, using data collected by the ATLAS experiment during the second data-taking period (Run 2) of the LHC, amounting to an integrated luminosity of 140/fb. Searching for Higgs boson pairs provides an excellent handle for understanding the fundamentals of the Higgs mechanism, and in particular for measuring the trilinear Higgs boson self-coupling λHHH, which is still largely unconstrained. [...]

ATLAS searches for di-Higgs production at 13 TeV and prospects for HL-LHC / Sano, Yuta (Graduate School of Science and Kobayashi-Maskawa Institute, Nagoya University) /ATLAS Collaboration
The latest results on production of Higgs boson pairs at 13 TeV by the ATLAS experiment are reported, including  a combination of six different decay modes. Results include bbtautau, bbbb, bbγγ, bbWW, WWWW and WWγγ final states, and they are interpreted both in terms of sensitivity to the SM and as limits on kappa_lambda, a scaling of the triple-Higgs interaction strength. [...]

Search for non-resonant pair production of Higgs bosons in the $b\bar{b}\gamma\gamma$ final state with the ATLAS detector / Jia, Zihang (Nanjing University (CN)) /ATLAS Collaboration
Since the discovery of the Higgs boson in 2012, a priority of the ATLAS and CMS Collaborations has been to better understand its properties and couplings, including those fundamental parameters that are related to interactions involving multiple Higgs bosons. A direct probe of the Higgs boson trilinear self-coupling is possible via Higgs boson pair production, making di-Higgs analyses particularly interesting. [...]

Search for di-Higgs production at 13 TeV and prospects for the HL-LHC / Grimm, Kathryn (California State University) /ATLAS Collaboration
Di-Higgs final states can arise through non-resonant production of two Higgs bosons and through potential heavy states decaying to two Higgs boson. This talk presents searches in several Higgs boson decay channels using Run2 Data at 13 TeV. [...]

Higgs self-coupling and prospects for HH and HHH / Pandini, Carlo (Nikhef National institute for subatomic physics (NL)) /ATLAS Collaboration
In this talk I will discuss current and future results for double and triple Higgs production from ATLAS and CMS, in the context of investigating the Higgs self-coupling parameter within the Standard Model..

ATLAS Liquid Argon Calorimeter Front-end electronics Phase-2 upgrade / Mazzeo, Elena (Università degli Studi e INFN Milano (IT)) ; ATLAS LAr Collaboration
A new era of hadron collisions will start around 2029 with the High-Luminosity LHC, which will allow to collect ten times more data than the amount that has been collected during the past 10 years of operation at LHC. [...]

Measurement prospects for di-Higgs production in the HH to bbyy channel with the ATLAS experiment at the HL-LHC / Wang, Alex Zeng (University of Wisconsin Madison (US)) /ATLAS Collaboration
We present a prospect study on di-Higgs production in the HH→bbγγ decay channel with the ATLAS experiment at the High Luminosity LHC (HL-LHC). The results are obtained by extrapolating the results from the Run 2 measurement, with 139 fb−1 of data at a center-of-mass energy of 13 TeV, to the conditions expected at the HL-LHC. [...]

Search for non-resonant di-Higgs production in the bbyy final state at 13 TeV with the ATLAS experiment / Pearkes, Jannicke Andree (SLAC National Accelerator Laboratory (US)) /ATLAS Collaboration
The bbγγ channel is one of the most sensitive HH final states for measuring the Higgs self-coupling and di-Higgs production cross-section. This analysis capitalizes on the clean signature of the two photons in the final state combined with the high branching ratio of H→bb. [...]

Probing the nature of electroweak symmetry breaking with Higgs boson pairs in ATLAS / Zabinski, Bartlomiej Henryk (Polish Academy of Sciences (PL))
Constraints on the Higgs boson self-coupling are set by combining double-Higgs boson analyses bb̄bb̄,bb̄τ + τ − and bb̄γγ decay channels The data used in these analyses were recorded by the ATLAS detector at the √ LHC in proton–proton collisions at s = 13 TeV and correspond to an integrated luminosity of 126–139 f b −1 .
