Description
Various extensions of the Standard Model predict the existence
of new types of quarks. We report on several search channels such as
vector-like quarks decaying to a Higgs boson and a top quark or to
a W boson and a b quark. The talk presents results from
searches for new resonances decaying to a top-antitop pair and a top-antibottom pair,
including the use of boosted top quark reconstruction techniques.
These searches use the data sample recorded in 2012 at sqrt(s)=8 TeV
centre-of-mass energy by the ATLAS experiment at the LHC.
