An elementary particle that is classified as a lepton, and has an extremely small but nonzero mass and no electric charge. It interacts with the surroundings only via the weak force or gravitation, making it very difficult to detect.

Example sentences
The underground neutrino detector was only sensitive to electron neutrinos, not to muon nor tau neutrinos.
It sounds like they though neutrinos were Weyl points, and neutrinos are real particles.
The other is to observe two neutrinos perfectly annihilate.
A few years ago it was a popular (unproved) idea in particle physics that the neutrinos were Majorana particles and so the neutrinos and the antineutrinos were the same particle.
We have also learned lots of stuff about neutrinos, like that they have mass and oscillate.
That leaves the neutrinos as the only known particles which could get mass this way.
Dark matter is no more a kludge than phlogiston, or the lumineferous aether, or neutrinos.
For example, superluminal neutrinos didn't prove special relativity false, although they did provide some evidence.
Neutrino oscillations were experimentally observed by shooting a beam of neutrinos through a long, narrow pile of photographic film at cern.
As long as it's not atoms, but eg just neutrinos, it's not really chemistry.
Except for neutrinos dark matter is NOT part of the current standard model.
There is still some debate about whether neutrinos are Weyl or Majorana fermions.
Quote examples
There are two clear "signatures" that neutrinos are Majoranas: one would be to observe these huge right-handed neutrinos.
When some scientists thought neutrinos traveled faster than light, they weren't called "light speed denialists".
So one of the most intriguing Majorana-mechanisms is the so-called "seesaw mechanism": this postulates some symmetry breaking between the left-handed neutrinos of the Standard Model and some new right-handed neutrinos; the left-handed get ratio m/M and the right-handed I think get ratio M/m and it all sort of balances out.
As far as the "Popularity" - I'm sure there are groups of theoretical physicists that work purely on the assumption of one or the other, but most treatments I've seen cover both the cases for Dirac and Majorana neutrinos, given that we don't have evidence one way or the other.
Proper noun examples
Neutrinos conclusively have mass since they experience flavor oscillations (if they were massless that would be impossible).
Neutrinos are one example of this kind of matter, so it seems reasonable that there are other kinds that are even more difficult to observe.
