Modifications to the neutrino mixing from the μ-τ reflection symmetry

The mu,tau reflection symmetry serves as a unique basis for understanding the observed neutrino mixing as it can lead us to the interesting results theta(23) = pi/4 and delta = -pi/2 which stand close to the current experimental results. But a precise measurement for theta(23) and delta will probably force us to modify the neutrino mixing U-(0) from such a symmetry. Here we perform a study for modifications to U-(0) in the forms of (UU(0))-U-(1-U-)dagger and (UU(1))-U-(0) where U-(1) = R-ij(()1) (for ij = 12, 23 and 13) with R-ij((1)) denoting a real orthogonal rotation on the ij plane.
