Light-front Hamiltonian formulation of electroweak theory

We develop the light-front Hamiltonian formulation of the electroweak theory with symmetry breaking through the Higgs mechanism. We quantize the theory using the method of Faddeev and Jackiw applicable to Hamiltonian systems with constraints. The starting point is the SU2 ⊗ U1 invariant Lagrangian which contains contributions from the massless Yang–Mills gauge boson sector, the massless fermion sector (leptons and quarks), the Higgs sector to break the SU2 ⊗ U1 symmetry and generate masses for the weak gauge bosons while leaving the photon massless, and the Yukawa sector to generate masses for the fermions.
