If Neutrinos are majorana particles, does this mean lepton number is not conserved?

Main Question or Discussion Point

If neutrinos are majorana particles does this mean that lepton number is not conserved in particle reactions? And I only noticed neutrinos are only produced when the decay of a particle to some other particles is carried by the W bosons ( weak interaction ).

Is it possible the weak interaction 'prefers' matter over antimatter somehow just like it prefers left handed particles and right handed antiparticles?

If. Conflicting unverifiable theories. I prefer theories that fit empirical results. Some studies postulated neutrinos oscillated between particle and antiparticle which would make it a Dirac Fermion not Majorana Fermion. I don't see why Lepton number changes since it is still a Fermion
"God did it" is just as verifiable as any theory out there explaining the preponderance of matter. As far as tested, there is no difference in the magnitude of matter or anti-matter properties that would advantage one over the other.

Sure, neutrinoless double beta decay would be the simplest example that comes to mind and is something actively looked for in experiments.

To put it in more technical terms, the weak interaction violates C and CP symmetry, yes.

I am not sure if weak interaction prefers matter over antimatter but I am sure it prefers left handed particles over right handed particles and right handed antiparticles over left handed antiparticles.

I dont understand how that is a response to what I wrote...
