摘要We propose a new pattern of the neutrino mixing matrix which can be parametrized as the product of an arbitrary Hermitian matrix and the well-known tribimaximal mixing matrix. In this scenario, nontrivial values of the smallest neutrino mixing angle theta(13) and the CP-violating phases entirely arise from the nonunitary corrections. We present a complete set of series expansion formulas for neutrino oscillation probabilities both in vacuum and in matter of constant density. We do a numerical analysis to show the nonunitary effects on neutrino oscillations. The possibility of determining small nonunitary perturbations and CP-violating phases is discussed by measuring neutrino oscillation probabilities and constructing "deformed unitarity triangles." Some brief comments on the nonunitary neutrino mixing matrix in the type-II seesaw models are also given.
