Description
The high energy frontier opened by the LHC is allowing us
to explore physics scenarios where new physics might lay.
The need to go beyond the Standard Model (SM) comes from
various unanswered questions, like where does the matter-antimatter
asymmetry comes from? What is the nature of Dark Matter?
How can the hierarchy problem be solved?
The recent discovery of an Higgs-like
boson tends to disfavour
the existence of a heavy
4th generation of quarks which would change the
Higgs SM cross section and branching ratio in a
way it is not experimentally observed.
At the same time, vector-like quarks become
a more compelling possibility due to their
important role stabilizing
the Higgs boson mass against radiative corrections.
The purpose of this poster is to review the
latest results in the searches for pair production
of vector-like quarks at the ATLAS experiment.
