[QUOTE="john baez, post: 6435035, member: 8778"] [B]TL;DR Summary:[/B] Here are some of the main open questions about neutrinos today. Merry Christmas! Neutrinos are mysterious. I just blogged about some of the big open questions involving neutrinos: [LIST] [*][URL='https://johncarlosbaez.wordpress.com/2020/12/24/neutrino-puzzles/']Neutrino puzzles[/URL]. [/LIST] In brief, nontechnical terms they are these: [LIST] [*]What is the correct theory of neutrinos? [*]Why are they almost but not quite massless? [*]Do all three known neutrinos—electron, muon, and tau—all have a mass? [*]Are the two neutrinos with very close masses the light ones, or the heavy ones? [*]Is any kind of neutrino its own antiparticle? [*]Are there right-handed neutrinos: that is, neutrinos that spin counterclockwise along their direction of motion when moving at high speeds? [*]Are there sterile neutrinos: that is, neutrinos that don't interact with other particles via the strong, weak or electromagnetic force? [/LIST] In my blog post I go into some more details. I'm looking for the best review articles on neutrino puzzles, to help update this physics FAQ: [LIST] [*][URL='https://math.ucr.edu/home/baez/physics/General/open_questions.html']Open questions in physics[/URL]. [/LIST] Do you know some good review articles? [/QUOTE]
