Description
Non-observation of vectorlike quarks (VLQs) at the LHC motivates us to look for possible gaps in their collider searches. We discuss a scenario where the VLQs decay substantially to a new singlet scalar (or pseudoscalar) that couples dominantly to the VLQs. Such a singlet state can be motivated in various BSM scenarios. The current mass limits on the VLQs ($1.2-1.6$ TeV, for various weak representations and decays) relax significantly if the VLQs have such additional decay(s). We present the current bounds on VLQs for this scenario and chart a model-independent roadmap to look for such VLQ decays. We also identify the possible signatures for pair-production searches and present a projection study for some promising channels for the weak-singlet top and bottom partner extensions at the HL-LHC.
