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 …

The current experimental data allow for a sub-TeV colorless weak-singlet scalar or
pseudoscalar. If such a singlet field is present together with TeV-range vectorlike top and …

Experimental searches for vector-like quarks have until now only considered their decays
into Standard Model particles. However, various new physics scenarios predict additional …

Composite Higgs models usually contain additional pseudo Nambu Goldstone bosons and
vector-like quarks. We discuss various aspects related to their LHC phenomenology and …

I review possible explanations of the muon g-2 anomaly in models with extended Higgs and
matter sectors, focusing on extensions of the standard model and the two Higgs doublet …

A comprehensive extension of the ordinary 2-Higgs Doublet Model (2HDM), supplemented
by vector-like quarks (VLQs), in the “alignment limit” is presented. In such a scenario, we …

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 …
