As I said "the principle of renormalizability "together" with various
symmetry principles OF the Standard Model "forbid" the neutrinos from having
masses.

So, in Standard Model there is no problem at all, but as I said "Standard
Model" "together" others various symmetry principles create troubles.

I've explained that in other messages you can read in this thread.

Thanks a lot John:)
