Search for displaced leptons in 13 TeV and 13.6 TeV $pp$ collisions with the ATLAS detector
A search for leptons, displaced from the primary interaction vertex, including data collected at a center-of-mass energy of 13.6~TeV by the ATLAS experiment during Run~3 of the Large Hadron Collider is presented. [...]

Measurements of W H and Z H Higgs production with decays into bottom quarks and direct constraints on the charm Yukawa coupling with 13 TeV collisions in the ATLAS detector.
A study of the Higgs boson decaying into bottom quarks ($H \to b\bar{b}$) and charm quarks ($H \to c\bar{c}$) is performed, in the associated production channel of the Higgs boson with a $W$ or $Z$ boson, using $140\,\mathrm{fb}^{-1}$ of proton-proton collision data at $\sqrt{s} = 13\,\mathrm{TeV}$ collected by the ATLAS detector.

Search for electroweak production of vector-like leptons in multiple tau and b-jets final states in $pp$ collisions at $\sqrt{s}$=13 TeV with the ATLAS detector
A search for vector-like leptons pair-production is presented, considering their decays into a third-generation Standard Model (SM ) quark and the vector leptoquark ($U_1$) as predicted by a renormalisable and ultraviolet-complete extension of the SM, dubbed as the '4321' model. [...]

Search for non-resonant Higgs boson pair production in final states with leptons, taus and photons in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector
A search is presented for non-resonant Higgs boson pair production, targeting the 4$V$ ($V$ = $W$ or $Z$), $VV\tau\tau$, 4$\tau$, $\gamma\gamma VV$ and $\gamma\gamma\tau\tau$ decay channels. [...]

Search for dark matter produced in association with a dark Higgs boson in the $b\bar{b}$ final state using $\sqrt{s}=13$ TeV collisions recorded with the ATLAS detector
A first dedicated search is performed for dark matter particles produced in association with a resonantly produced pair of b-quarks with $m_{bb} < 150$ GeV using 140 fb$^{-1}$ of proton-proton collisions recorded by the ATLAS detector at a center-of-mass energy of 13 TeV. [...]

Search for pair production of boosted Higgs bosons via vector-boson fusion production in the $b\bar{b}b\bar{b}$ final state using $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector
A search for Higgs boson ($H$) pair production via vector boson fusion (VBF) is performed in the Lorentz-boosted regime, where a Higgs boson candidate is reconstructed as a single large-radius jet, using 140 fb$^{-1}$ of proton-proton collision data at 13 TeV recorded by the ATLAS detector. [...]
