Hi, Could someone tell me approximately what the mass of a neutrino is? Or when we’ll get that value?. Are there any experiments currently trying to get that value?.
If anyone could, they’d have a Nobel prize. Upper limit as far as I know is 0.45 eV from the KATRIN experiment
Thanks for your reply. I did not know that information.
Could a negative energy value be a lower limit for the
neutrino mass (for example -0.3 eV)?
No. It’s telling you that analysis gives a result consistent with zero. I would encourage you to look up the original papers and read them. Google Scholar (scholar.google.com) would be an excellent resource to type in your questions.
Okay, thank you very much for your reply. Thanks for the recommendation.
