Can somebody explain to me how much mass neutrinos have. According to my understanding neutrinos oscillate, therefore they should have some mass. If this is right then how much mass do they have?
Answer
The particle data group has a thorough article on neutrino oscillation experiments.
Oscillations are the way to measure mass differences between neutrinos, and in table 13.7 experimental values are given for delta(m^2) of the three neutrino species. These put a lower limit to the mass values.
From the definition it is obvious that the limits are of the order of electron volt or less, for the "heavier ones".
The experiments are not simple.
