1, Sect. 8). In QED, we saw that the gauge invariance controlled the divergence in order to not grow faster than the logarithm of the momenta. There, the gauge propagator behaved like 1/ k 2 and the divergences were removed by introducing a few number of counter terms, in other words, the theory was renormalizable (see Vol. 1, Chapt. 8). However, presence of the longitudinal polarization adds an extra diverging contribution. This is why the unitarity of the process involving the massive gauge boson is broken.

2). Spinor indices for fermions are sometimes omitted. 3, depending on the particle species. For fermions, the sign of momentum follows that of an arrow. Feynman Rule 3: Fermion-Gauge Boson Vertices For vertices of fermions and gauge bosons, we attach coupling constants and appropriate γ factors (Fig. 4). 2 Wave functions to fermions and polarization vectors to bosons are to be attached to each external line. 3 Propagators are to be attached to each internal line. 23 24 1 The Standard Model type.

All we need to recognize is that fermions of different chirality carry different charges. 2 Weak Charge and SU(2) U(1) Symmetry As an example, let us consider the chiral gauge transformation which follows the U(1) symmetry and denote the charge operator as “Y” (call it hypercharge). Then, the gauge transformation for the fermion field f D ψf or scalar φ is 1) f L ! φ De iαY fR ! 3) where Y( f L ), and so on, are the hypercharges that each field carries. We said that the weak charge comes in two varieties and respects the SU(2) symmetry.
