In this study, we propose a model-independent framework to search for vectorlike B-quarks (VLQ-B) through resonant production via b-gluon fusion, and explore the potential signals through the B -> tW decay mode.
New vectorlike quarks have been proposed in many scenarios of new physics beyond the Standard Model, which address the hierarchy problem and may be potentially discovered at the Large Hadron Collider (LHC). Based on a model-independent framework, we propose to search for the vectorlike B-quark (VLQ-B) and focus on resonant production via b-gluon fusion through chromomagnetic interactions. We then explore the possible signals of the VLQ-B through the B -> tW decay mode at the 14 TeV LHC. After a rapid simulation of signal and background events, the 2 sigma excluded regions and the 5 sigma discovery reach in the parameter plane of K-B - M-B are obtained at the LHC with an integrated luminosity of 300 (3000) fb(-1) in the dilepton final states.
