Searches for vector-like quarks at the LHC need to move beyond considering only decays to Standard Model particles and incorporate exotic decay channels involving new physics scenarios, such as those predicted by composite Higgs models, to accurately assess their existence and potential impact.
This study investigates the phenomenological implications of introducing Vector-Like Bottom Quarks (VLBs) within the framework of a Two Higgs Doublet Model (2HDM) Type-II, specifically focusing on their unique decay signatures at the Large Hadron Collider (LHC) in the alignment limit and their potential to unveil Beyond the Standard Model (BSM) physics.
