Back on lecture about Standard model, professor said that original Weinberg-Salam-Glashow theory had to be augmented with Higgs mechanism because it didnt give rise to massive gauge fields, yet since weak interaction had finite range they knew it had to have a massive carrier, well three of them due to three SU(2) generators. When I asked him why massive carrier implies finite range, and massless infinite, I didnt get satisfactory (any) explanation.(adsbygoogle = window.adsbygoogle || []).push({});

So, can anyone please shed any light on this subject?
