We review the theory and phenomenology of isosinglet vector-like quarks (VLQs). In recent
years, interest in VLQs has been increasing, due to their contributions to new physics effects …

A bstract We investigate the pair production of a vector-like quark triplet with hypercharge
5/3 decaying into top quark and a complex scalar triplet with hypercharge 1 at the LHC. This …

The presence of a new decay mode relaxes the current mass exclusion limits on vectorlike
quarks considerably. We consider the case of a weak-singlet vectorlike B quark that can …

The possibility of a vectorlike top partner decaying to a new colorless weak-singlet scalar or
pseudoscalar has attracted some attention in the literature. We investigate the production of …

In this work, we have considered an extension of the standard model (SM) with a SU (2) L
singlet vectorlike quark (VLQ) with electric charge Q=+ 2/3. The model also contains an …

Vector-like quarks (VLQs) are a common feature of many scenarios of new physics beyond
the Standard Model (SM), which generally decay into a SM third-generation quark with a SM …

Vectorlike quarks have been predicted in various new physics scenarios beyond the
Standard Model. In a simplified modelling of a (B, Y) doublet including a vectorlike quark Y …

New vectorlike T-quarks (VLQ-T) have been predicted in many scenarios of new physics
beyond the Standard Model, the current mass exclusion limits from LHC experiments will be …

In this paper, we study the discovery potential of a Vector-Like B quark (VLB) via the process
pp→ B (→ b Z) j→ b (Z→ ν l ν l¯) j at the Large Hadron Collider (LHC) with s= 14 TeV. In the …

We use machine learning techniques to identify a boosted dark photon jet as a signature of
a heavy vector-like fermionic portal matter (PM) connecting the visible and the dark sectors …
