Bardeen, Hill, and Lindner proposed that these Standard Model particles may form condensates that break electroweak symmetry, generating a composite Higgs boson.  In many contemporary models, they are viewed as composite objects with new strong interactions not felt by other known fermions.  For instance, Sundrum and Agashe recently proposed that the right-handed one and the Higgs are composite.  It has been suggested that their abnormally large mass comes from an infrared fixed point of renormalization group flow.  They generally decay to a W boson and a bottom quark, and the left-handed one is in a doublet with the left-handed bottom quark.  FTP, what is this heaviest of the six flavors of quarks?
