Title: Dynamical Electroweak Symmetry Breaking with a Heavy Fermion in Light of Recent LHC Results

The recent announcement of a discovery of a possible Higgs-like particle鈥攊ts spin and parity are yet to be determined鈥攁t the LHC with a mass of 126鈥塆eV necessitates a fresh look at the nature of the electroweak symmetry breaking, in particular if this newly-discovered particle will turn out to have the quantum numbers of a Standard Model Higgs boson. Even if it were a 0 + scalar with the properties expected for a SM Higgs boson, there is still the quintessential hierarchy problem that one has to deal with and which, by itself, suggests a new physics energy scale around 1鈥塗eV. This paper presents a minireview of one possible scenario: the formation of a fermion-antifermion condensate coming from a very heavy fourth generation, carrying the quantum number of the SM Higgs field, and thus breaking the electroweak symmetry.
