We calculate contributions to the anomalous magnetic moment of the muon from heavy
neutral and charged Higgs bosons and new leptons in two-Higgs-doublet models extended …

A bstract In this work, we obtain the current limits on the pair production of vectorlike leptons
decaying to a Standard Model gauge boson and a lepton in the second generation using the …

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 …

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 …

We study the phenomenology of charged Higgs bosons (H±) and vectorlike quarks (VLQs),
denoted as T, the latter possessing a charge identical to the top quark one, within the …

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 …

A bstract We demonstrate the potential of fully leptonic cascade decays of a heavy neutral
Higgs boson through vectorlike leptons as a simultaneous probe for extended Higgs sectors …
