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 singly produced vector-like top partners in multilepton final states with 139 $\mathrm{fb}^{-1}$ of $pp$ collision data at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
A search for the single production of a vector-like top partner ($T$) decaying into a $Z$ boson and a top quark is presented, using the full Run 2 dataset corresponding to 139 $\mathrm{fb}^{-1}$ of $pp$ collisions at $\sqrt{s} = 13$ TeV, collected in 2015-2018 with the ATLAS detector at the Large Hadron Collider. The targeted final state is characterized by the presence of a pair of electrons or muons with opposite-sign charges which form a $Z$-boson candidate, as well as by the presence of $b$-tagged jets and forward jets. [...]

Search for single production of vector-like quarks decaying into $Wb$ in $pp$ collisions at $\sqrt{s} =$ 13 TeV with the ATLAS detector
A search for singly-produced vector-like quarks $Q$, where $Q$ can be either a $T$ quark with charge $2/3$ or a $Y$ quark with charge $4/3$, is performed in 3.2 $fb^{-1}$ of proton--proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the LHC. [...]

Searches for leptoquarks and heavy leptons with the ATLAS detector at the LHC / Grancagnolo, Sergio (Institute of Physics, Humboldt University, Berlin)
Searches of vector-like leptons, heavy Majorana neutrinos, and leptoquarks, using the complete $20.3~fb^{-1}$ luminosity sample of $pp$ collisions collected at $8\mathrm{\ Te\kern -0.1em V}$ by the ATLAS detector, are presented in this review. [...]

Searches for new phenomena with heavy quarks and multileptons at the LHC / Valery, Loic (Institut de Fisica d'Altes Energies, Universitat Autonoma de Barcelona)
This talk presents searches for heavy vector-like quarks as well as top-related searches for new physics. Two recent searches, performed in the one-lepton channel are presented, and a particular emphasize is put on the searches in the context of multi-lepton final states..
