I assume that dark matter is made of heavy neutrinos.But wouldnt they be converted into neutrinos with less mass throygh weak interaction?So dark matter isnt made of neutrinos.I think there is truly a new fundamental particle a fermion we havent detected yet a dark particle with 0 charge and with a magnetic moment of 0.

  • $\begingroup$ For the three neutrinos we have, muon neutrinos don't decay into electron neutrinos; they oscillate. This is because each variety of neutrino is made up of mass eigenstates, and the heavier eigenstates don't decay into the light eigenstates. $\endgroup$ – Peter Shor Jun 2 at 10:18
  • $\begingroup$ Yes because they have pretty much the same mass. $\endgroup$ – Flawless Jun 2 at 10:21
  • $\begingroup$ And only by measurement we can understand if a neutrino is an electron neutrino,tau neutrino or muon neutrino.I am saying a hypothetical neutrino with a mass of a quark. $\endgroup$ – Flawless Jun 2 at 10:23
  • $\begingroup$ There are conserved quantities in physics. This is why protons don't decay to positrons (baryon number conservation, lepton number conservation, etc..) Conserved quantities could explain why super-heavy neutrinos don't decay to standard neutrinos. $\endgroup$ – Peter Shor Jun 2 at 10:24

    $\begingroup$ So you've deduced your own rules for physics involving "similar particles" and "pretty much the same mass." This site answers questions using mainstream physics, in which it is believed that conservation rules (and not "having pretty much the same mass") keeps muon neutrinos from decaying into electron neutrinos. We are not going to be able to help you with your own theories of non-mainstream physics. We don't understand them; they're not the theories we learned. See the help page. $\endgroup$ – Peter Shor Jun 2 at 10:38

As written this isn't exactly a question but if you are trying to ask "what is dark matter made of?" then the answer is no one knows. It is an open research question.

I assume that dark matter is made of heavy neutrinos.

Within the Standard Model there are no heavy neutrinos. A model beyond the standard model is necessary to posit heavy neutrinos.

One of the models for constituents of dark matter uses supersymmetry with R parity conservation. The lightest supersymmetric particle to which R parity conservation constrains supersymmetric parcicles to decay is called LSP, (lightest supersymmetric particle) . Various candidates depending on the specific model are proposed. These models are a matter of current research. The search for supersymmetry is going on in the LHC data.

But wouldnt they be converted into neutrinos with less mass throygh weak interaction

No, the LSP cannot decay because of R parity conservation, by construction of the model because it is needed to explain dark matter.

Supersymmetry is beyond the standard model, and also beyond current observations. The LSP will be a new particle, if it is seen in experiments.

Everything about dark matter is under research.

    $\begingroup$ @Flawless Neutralinos are fermions. You can start learning about them at en.wikipedia.org/wiki/Neutralino though I recommend that you don't stop there. $\endgroup$ – David Schaich Jun 2 at 12:11

    $\begingroup$ @Flawless as david corrected me, it is the sneutrino that is the boson partner of the neutrino. read his comment where he corrected me. $\endgroup$ – anna v Jun 2 at 13:02
