4.6. WEAK INTERACTION THEORY 251
Obviously, it is not reality.
4.Artificial Higgs mechanism.In the classical electroweak action (4.6.55)-(4.6.57), the
Higgs sectorLHis not based on a first principle, and is artificially added into the action.
5.Presence of a massless and charged bosonφ+.In the WS theory, the Higgs scalar
doubletφ= (φ+φ^0 )contains a massless bosonφ+with positive electric charge. Obviously
there are no such particles in reality. In particular, the particleφ+is ”formally suppressed” in
the WS theory by transforming it to zero in the WS theory. However, from a field theoretical
point of view, this particle field still represents a particle. This is one of major flaws for the
electroweak theory and for the standard model.
