Top quarks and electroweak symmetry breaking in little Higgs models

“Little Higgs” models, in which the Higgs particle arises as a pseudo Goldstone boson, have a natural mechanism of electroweak symmetry breaking associated with the large value of the top quark Yukawa coupling. The mechanism typically involves a new heavy $\mathrm{SU}{\mathrm{}\left(2\right)\mathrm{}}_L$ singlet top quark T. We discuss the relationship of the Higgs boson and the two top quarks. We suggest experimental tests of the little Higgs mechanism of electroweak symmetry breaking using the production and decay of the T at the CERN Large Hadron Collider.
