“…All these parameters are contained within, U , the so called Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix or lepton mixing matrix which under Standard parametrization, appears as shown, U = R 23 (θ 23 )U 13 (θ 13 : δ)R 12 (θ 12 ).P, (1) where, P is the diagonal matrix that shelters the two Majorana phases. In symmetry basis, where both charged lepton and neutrino mass matrices are considered as non-diagonal, one can identify the lepton mixing matrix, U = U † lL .U ν [42][43][44][45][46][47][48], where, U lL is the left handed charged lepton diagonalizing matrix and U ν is the neutrino mixing matrix. If it is the flavor basis, only charged lepton mass matrix is diagonal, and one sees, U = U ν .…”
