Direct search implications for a custodially-embedded composite top
We assess current experimental constraints on the bidoublet+singlet model of top compositeness previously proposed in the literature. This model extends the Standard Model's spectrum by adding a custodially embedded vectorlike electroweak bidoublet of quarks and a vectorlike electroweak singlet...

| description | We assess current experimental constraints on the bidoublet+singlet model of top compositeness previously proposed in the literature. This model extends the Standard Model's spectrum by adding a custodially embedded vectorlike electroweak bidoublet of quarks and a vectorlike electroweak singlet quark. While either of those states alone would produce a model in tension with constraints from precision electroweak data, in combination they can produce a viable model. We show that current precision electroweak data, in the wake of the Higgs discovery, accommodate the model and we explore the impact of direct collider searches for the partners of the top quark. |
