Some simple mixing and mass matrices for neutrinos

We argue that the accumulated neutrino data, including recent results from KamLAND and K2K, point to a neutrino mixing matrix with (V11,V21,V31; V21,V22,V32; V13,V23,V33)=(−2/6,1/6,1/6; 1/3,1/3,1/3; 0,1/2,−1/2). We propose some simple neutrino mass matrices which predict such a mixing matrix.
