Phenomenology of Neutrino Oscillations

Neutrino Masses and Flavor Mixing

“…in which α = β running over (e, μ, τ ) and i = j running over (1,2,3). The implication of this result is very obvious: the information about leptonic CP violation can in principle be extracted from the measured moduli of the neutrino mixing matrix elements.…”

“…A striking consequence of the non-unitarity of V is the loss of universality for the Jarlskog invariants of CP violation, J ij αβ ≡ Im(V αi V βj V * αj V * βi ), where the Greek indices run over (e, μ, τ ) and the Latin indices run over (1,2,3). For example, the extra CP-violating phases of V are possible to give rise to a significant asymmetry between ν μ → ν τ and ν μ → ν τ oscillations.…”
