Abstract:

It is investigated in canonical formalism what operator corresponds to the actually observalbe electro-magnetic field strength in the Weinberg-Salam model. It is pointed out that the naive definition F^el_µν≡∂_µA_ν^ph-∂_νA_µ^ph with A_µ^ph=(g²+g'²)^-1/2(gw_µ⁰+g'W_µ³) is not BRS invariant and cannot meet the requirement of observability. A possible condidate operator is proposed.
