Probability distributions of different neutrino mass models (IMAGE)
Caption
The horizontal axis shows the ordinary logarithm of the neutrino mass squared difference ratio, while the vertical axis shows their probability distribution. Each histograms represent the probability distributions for the seesaw mechanisms of the corresponding color. The vertical red and blue lines represent the experimental values (1σ and 3σ errors) of the ordinary logarithm of the neutrino mass squared difference ratio. The probability distribution for the seesaw model with the random Dirac and Majorana matrices in orange has the highest probability of reproducing the experimental value.
