a result of the decay of a heavy particle, has become an essential part of collider studies …

Machine learning-enhanced search for a vectorlike singlet quark decaying to a singlet scalar or pseudoscalar

J Bardhan, T Mandal, S Mitra, C Neeraj - Physical Review D, 2023 - APS
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 …

Pair production of the singlet vector-like B quark at the CLIC

JZ Han, YB Liu, SY Xu - The European Physical Journal C, 2024 - Springer
Vector-like quarks (VLQs) are a common feature of many scenarios of new physics beyond
