  The ATLAS and CMS collaborations at the LHC have performed analyses on the
existing data sets, studying the case of one vector-like fermion or multiplet
coupling to the standard model Yukawa sector. In the near future, with more
data available, these experimental collaborations will start to investigate
more realistic cases. The presence of more than one extra vector-like multiplet
is indeed a common situation in many extensions of the standard model. The
interplay of these vector-like multiplet between precision electroweak bounds,
flavour and collider phenomenology is a important question in view of
establishing bounds or for the discovery of physics beyond the standard model.
In this work we study the phenomenological consequences of the presence of two
vector-like multiplets. We analyse the constraints on such scenarios from
tree-level data and oblique corrections for the case of mixing to each of the
SM generations. In the present work, we limit to scenarios with two top-like
partners and no mixing in the down-sector.
