Vector-like quarks, leptoquarks and new gauge bosons searches in ATLAS / Haley, Joseph (Oklahoma State University (US)) /ATLAS Collaboration
The Standard Model of Particle Physics explains many natural phenomena yet remains incomplete. Leptoquarks (LQs) are hypothetical particles predicted to mediate interactions between quarks and leptons, bridging the gap between the two fundamental classes of particles. [...]

Search for pair-produced vector-like quarks coupling to light quarks in the lepton plus jets final state using 13 TeV $pp$ collisions with the ATLAS detector / ATLAS Collaboration
A search is presented for the pair-production of heavy vector-like quarks (VLQs) that each decay into a $W$ boson and a light quark. This study focuses on events where one $W$ boson decays into leptons and the other into hadrons. [...]

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 pair-production of vector-like quarks in lepton+jets final states containing at least one $b$-jet using the Run 2 data from the ATLAS experiment
A search is presented for the pair-production of heavy vector-like quarks in the lepton+jets final state using 140 fb$^{-1}$ of proton–proton collision data with $\sqrt{s}= 13$ TeV collected with the ATLAS detector. [...]

VLQ searches and hadronic final states in the ATLAS experiment / Ellajosyula, Venugopal (Uppsala University (SE)) /ATLAS Collaboration
Several models which go beyond the Standard Model (BSM) predict the existence of Vector-like quarks (VLQs). One such class of models, known as Composite Higgs Models (CHMs), attempts to reduce the fine-tuning of the mass of the Higgs boson. [...]

Searches for new phenomena in final states with 3rd generation quarks using the ATLAS detector / Gadow, Philipp (CERN) /ATLAS Collaboration
Many theories beyond the Standard Model predict new phenomena, such as heavy vectors or scalar, vector-like quarks, and leptoquarks in final states containing bottom or top quarks. Such final states offer great potential to reduce the Standard Model background, although with significant challenges in reconstructing and identifying the decay products and modelling the remaining background.

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 $T$ quarks decaying into $Ht$ or $Zt$ in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
This paper describes a search for the single production of an up-type vector-like quark ($T$) decaying as $T \rightarrow Ht$ or $T \rightarrow Zt$. The search utilises a dataset of $pp$ collisions at $\sqrt{s}=13$ TeV collected with the ATLAS detector during the 2015-2018 data-taking period of the Large Hadron Collider, corresponding to an integrated luminosityof 139 fb$^{-1}$.
