Higgs mechanism

[touqra]

Are there any other mechanisms apart from Higgs mechanism that explains the spontaneous symmetry breaking making photon massless and W and Z bosons massive?
Do you really believe in the Higgs mechanism?

[selfAdjoint]

I'll believe in the Higgs mechanism when Tevatron or LHC finds the (or a) Higgs particle. While there's a paper published on the arxiv every now and then suggesting some other means of generating mass, none of them have reached acceptance in the physics community. Today just about all particle physicists explain all particle masses by the Higgs mechanism.
