Neutrinos are observed to oscillate in flavour as
they propagate. The theory showing why this implies
neutrinos must have mass can be found on
the PDG website pdg.lbl.gov on their "reviews"
page. In essence, it shows how a neutrino of
definite flavour produced with definite 3-momentum
must then evolve into a superposition of flavours
as it propagates, but only if the mass eigenstates
of the neutrinos differ, i.e: have different non-zero
masses.
If your theory says that neutrinos have
mass=0, then you must show where/how the theory
on the PDG website is wrong, or you must account
for neutrino flavour oscillation by some other
mechanism.
