Yw. Kim et al., HAMILTONIAN EMBEDDING OF THE SU(2) HIGGS-MODEL IN THE UNITARY GAUGE, Journal of physics. G, Nuclear and particle physics, 24(5), 1998, pp. 953-961
Following systematically the generalized Hamiltonian approach of Batal
in, Fradkin and Tyutin, we embed the second-class non-Abelian SU(2) Hi
ggs model in the unitary gauge into a gauge invariant theory. The stro
ngly involutive Hamiltonian and constraints are obtained as an infinit
e power series in the auxiliary fields. Furthermore, comparing these r
esults with those obtained from the gauged second-class Lagrangian, we
arrive at a simple interpretation for the first-class Hamiltonian, co
nstraints and observables.
