Neutrinos are Weyl particles!

In about 1994 I tried to explain to a friend the nature of Majorana neutrinos,
and in particular the "well known fact" that for massless neutrinos Majorana and
Weyl neutrinos are equivalent. At that time I was absolutely sure I understood
this issue quite well. In spite of this after posing me some questions she said: "You know what Rainer,
I feel you do not really understand this deeply." I became a bit angry: "No, *you* are
too dumb to understand." A few days later I came back to her and said:
"I am sorry: you were right, I did not understand it at all."
The matter really bugged me and I discussed it in the next two years with
a couple of knowledgable specialists. In this exchange I shared the feelings of my friend.
(This was the instinct of a first-year student who immediately notice when the professor
doesn't know what he's talking about, even if she doesn't know the first thing about the subject.)
In 1996 I wrote a manuscript about this issue that came to the conclusion
that neutrinos are Weyl particles, and that this can be shown even in the massless
case. This  paper was wrong. In 2001 after countless further discussions I submitted
correction (pdf) that reaches the same conclusion but only when making stronger assumptions.
I also realised neutrinos can have Majorana masses without being Majorana fermions.
A short summary of my main conclusions, links to various papers, disussion with
specialists and an explanation where I erred in the first manuscript can be found  here .
I failed dismally to convince the community, though the issue seems (by now) very
clear to me. A close colleagues, who knows that I am no fool, refused to take a look
at it because the issue is "so well understood". In conclusion the whole matter seems
to be a prime example for the correctness of Popper's motto of this site.
