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 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. [...]

Searches for New Phenomena in Final States with 3rd Generation Quarks using the ATLAS Detector / Haley, Joseph (Oklahoma State University (US)) /ATLAS Collaboration
Many theories beyond the Standard Model predict new phenomena, such as heavy vectors or scalar, and vector-like quarks, 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 Vector-Like Quarks / Henkelmann, Steffen (University of British Columbia) /ATLAS Collaboration
Vector-like quarks appear in many theories beyond the Standard Model as a way to cancel the mass divergence for the Higgs boson. The current status of the ATLAS searches for the production of vector-like quarks will be reviewed for proton-proton collisions at 13 TeV. [...]

Searches for new physics with top- and bottom-quark signatures using the ATLAS detector / Fassi, Farida (University Mohammed V)
High-mass resonances or new particles decaying into top- and/or bottom-quark + X are predicted in many new physics scenarios including extended gauge models, extra dimensions, 2HDM, etc. The vector-like quarks (VLQs), preferentially coupled to the third generation SM quarks, are also predicted e.g, in composite Higgs models as a “natural” way to stabilise the Higgs boson mass. [...]

Searches for vector-like quarks with the ATLAS detector / Haley, Joseph (Oklahoma State University (US)) /ATLAS Collaboration
Vector like quarks appear in many theories beyond the Standard Model as a way to cancel the mass divergence for the Higgs boson. The talk will focus on the most recent results using 13 TeV pp collision data collected by the ATLAS detector. [...]

BSM searches relevant for flavour physics / Pleskot, Vojtech (Charles University (CZ)) /ATLAS Collaboration
Many theories beyond the Standard Model predict new phenomena with a particular flavour structure, such as heavy vectors or scalar, vector-like quarks, vector-like leptons, and leptoquarks, that could address some of the shortcomings of the SM and could potentially explain some of the observed tensions in the particle physics landscape. The recent 13 TeV pp results, along with the associated improvements in identification techniques, will be reported..

Machine Learning Multi-Stage Classification and Regression in the Search for Vector-like Quarks and the Neyman Construction in Signal Searches / Leone, Robert Matthew
A search for vector-like quarks (VLQs) decaying to a Z boson using multi-stage machine learning was compared to a search using a standard square cuts search strategy [...]
