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. [...]

Search for vector-like quarks, heavy neutral leptons and long-lived particles in ATLAS and CMS experiments / Grancagnolo, Sergio (INFN Lecce e Universita del Salento (IT)) /ATLAS Collaboration
Various theories beyond the Standard Model predict heavy neutral leptons, or long-lived particles with unique signatures which are difficult to reconstruct. Another area of interest are vector-like quarks (VLQs) which lie at the heart of many extensions to the Standard Model seeking to address the Hierarchy Problem, as they can naturally cancel the mass divergence for the Higgs boson. [...]

Search for heavy neutral leptons in decays of $W$ bosons using a dilepton displaced vertex in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector / ATLAS Collaboration
A search for a long-lived, heavy neutral lepton ($\mathcal{N}$) in 139 fb$^{-1}$ of $\sqrt{s}=13$ TeV $pp$ collision data collected by the ATLAS detector at the Large Hadron Collider is reported. The $\mathcal{N}$ is produced via $W \rightarrow \mathcal{N} \mu$ or $W \rightarrow \mathcal{N} e$ and decays into two charged leptons and a neutrino, forming a displaced vertex. [...]

Displaced Vertex Search for Heavy Neutral Leptons with the ATLAS Detector / Trischuk, Dominique Anderson (University of British Columbia (CA)) /ATLAS Collaboration
This talk will present recent results of a search for long-lived heavy neutral leptons (HNLs) in proton-proton collisions at the Large Hadron Collider (LHC). The Standard Model (SM) of particle physics is an extremely successful theory and its major predictions have been precisely confirmed. [...]

Searches for BSM physics using challenging and long-lived signatures with the ATLAS detector / Grancagnolo, Sergio (Humboldt University of Berlin (DE)) /ATLAS Collaboration
Various theories beyond the Standard Model predict new, long-lived particles with unique signatures which are difficult to reconstruct and for which estimating the background rates is also a challenge. Signatures from displaced and/or delayed decays anywhere from the inner detector to the muon spectrometer, as well as those of new particles with fractional or multiple values of the charge of the electron or high mass stable charged particles are all examples of experimentally demanding signatures.

Search for displaced lepton jets with the ATLAS experiment / Salvatore, Daniela (INFN Gruppo Collegato di Cosenza and Universita' della Calabria, Dipartimento di Fisica) /ATLAS Collaboration
Several possible extensions of the Standard Model predict the existence of a dark sector that is weakly coupled to the visible one: i.e. the two sectors couple via the vector portal, where a dark photon with mass in the MeV to GeV range mixes kinetically with the SM photon. [...]
