There is also a weak isospin conservation law: all weak interactions must preserve the weak isospin.

But the spontaneously broken vacuum contains a charge condensate of Higgs bosons with nonzero weak isospin. If we take this charge condensate into account, weak isospin is still conserved, but it we don't, we can have a left handed electron (isospin I₃=-1/2) oscillating into a right handed electron (I₃=0). What "really" happens is the left-handed electron "emits" a Higgs boson (with I₃=-1/2) and turns into a right-handed electron, but the "emitted" Higgs boson enters the condensate and becomes undetectable because the number of Higgs boson in the charge condensate is undetermined.
