Here's my understanding: In a frame where the neutrino is stationary, it has a fixed mass equal to its energy. This is its total energy. It is split into three parts \(E=E_1+ E_2+ E_3\), which remain fixed for the lifetime of the neutrino. If we were to weigh such a neutrino (e.g., in a gravitational field) we'd get a number that is somewhere between the lightest and the heaviest mass eigenstates (assuming they are positive). And this mass is different for each particular neutrino, depending on the kinetics of the process that produced it. Is that correct?
