Why is the top quark much heavier than other fermions?    [PDF]

The recent ALTAS and CMS experiments show the first observations of a new particle in the search for the standard model Higgs boson at the LHC. We revisit the theoretical inconsistency of the fundamental high-energy cutoff with the parity-violating gauge symmetry of local quantum field theory for the standard model. This inconsistency suggests high-dimension operators of fermion interactions, attributing to the quantum gravity. In this Letter, we review the dynamical symmetry breaking mechanism and show that it is an energetically favorable configuration for the top quark acquiring its mass via spontaneous symmetry breaking, while other fermions acquiring their masses via explicit symmetry breaking.
