Exotic LHC signatures for partial compositeness
Composite Higgs models together with partial compositeness predict the existence of new scalars and vector-like quarks (VLQ) around the TeV scale. Generically, the presence of these additional scalars opens up new decay topologies for the VLQs. In this talk I will first review the basic features of partial compositeness in the context of 4D confining gauge theories. Then I will present a generic TeV scale Lagrangian to capture the phenomenological signatures of VLQs in this class of models. I will also present the current status of the VLQ search at the LHC, their limitations and scope for extensions. Finally, I will focus on a concrete model to show that the VLQs in this model can have significant branching ratios to additional new scalars and a third generation quark, compared to the usual Standard Model channels.
