Initially there were mathematical reasons why people suspected that all <boson> needed to have 0 mass as is the case for <photons> a <gluons>, see <Goldstone's theorem>.

However, experiments showed that the <W boson> and the <Z boson> both has large non-zero masses.

So people started theorizing some hack that would fix up the equations, and they came up with the <higgs mechanism>.
