HAMILTONIAN EMBEDDING OF THE SU(2) HIGGS-MODEL IN THE UNITARY GAUGE

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.
