Experimental searches for vector-like quarks have until now only considered their decays into Standard Model particles. However, various new physics scenarios predict additional scalars, so that these vector-like quarks can decay to new channels. These new channels reduce the branching ratios into Standard Model final states, significantly affecting current mass bounds. In this article, we quantitatively assess the relevance and observability of single and pair production processes of vector-like quarks, followed by decays into both standard and exotic final states. We highlight the importance of large widths and the relative interaction strengths with Standard Model particles and new scalars. Then, we review the post-Moriond 2024 status of these models in light of available LHC data and discuss potential future strategies to enhance the scope of vector-like quark searches.

Search for pair-production of vector-like $T$ quarks decaying into a top quark and a spin-0 particle in the diphoton final state in proton proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
No excess is observed in a first ATLAS search for pair-produced vector-like T quarks decaying via an exotic spin-0 particle to diphotons; fiducial cross-section limits and a model exclusion up to m_T≈1620 GeV are set.

Towards UV-Models of Kinetic Mixing and Portal Matter VII: A Light Dark Photon in the $3_c3_L1_A1_B$ Model
In the 3c3L1A1B model, a single larger gauge force unifies part of the weak force with a dark force, producing a light dark photon, multi-TeV portal matter, and new heavy gauge bosons with testable signatures.

Dark matter in composite Higgs models with a scotogenic EFT
In the SU(6)/Sp(6) composite Higgs model with a scotogenic Z2, three of four neutral pseudo-Goldstone dark matter candidates can reproduce the observed relic density, while the SU(2)L triplet candidate fails; spin-1 r...

Higgs Yukawa coupling constraints on a benchmark one-loop radiative mass model for the bottom, charm and tau
A radiative one-loop mass model for b, c, τ, and ντ remains consistent with current Higgs and EW data, and future Yukawa-precision measurements are projected to tighten, but not close, its viable parameter space.

Searching for single production of vectorlike quarks decaying into Wb at a future muon-proton collider
A future muon-proton collider could discover singly produced vectorlike quarks T and Y decaying to Wb up to masses near 3.8 to 4.1 TeV and exclude them up to 4.5 to 4.8 TeV in a simplified two-parameter model.
