Dynamical Symmetry Breaking by SU(2) Gauge Bosons.
This work explores the possibility of obtaining a mass gap in SU(2) Yang-Mills theory from the intrinsic gauge bosons, without invoking a separate Higgs boson or fermion-antifermion pairs. The quadratic and quartic gauge boson self-interactions form a potential that leads to finite vacuum expectation values (VEVs). Transverse polarization of the VEVs ensures Lorentz invariance of the vacuum. Pairs of gauge bosons in the spin and isospin singlet state form a composite Higgs boson. It can be viewed as the simplest possible glueball in Yang-Mills gauge theories. The gauge boson potential is convertible to the standard Higgs potential. Compatibility of the two potentials determines their quadratic and quartic coupling constants.
