| 英文摘要 | In view of the latest t2k and minos neutrino oscillation data which hint at a relatively large theta(13), we perform a systematic study of the majorana neutrino mass matrix m-nu with two independent texture zeros. we show that three neutrino masses (m(1), m(2), m(3)) and three cp-violating phases (delta, rho, sigma) can fully be determined from two neutrino masss-quared differences (delta m(2), delta m(2)) and three flavor mixing angles (theta(12), theta(23), theta(13)). we find that seven patterns of m-nu (i.e., a(1,2), b-1,b-2,b-3,b-4 and c) are compatible with current experimental data at the 3 sigma level, but the parameter space of each pattern is more strictly constrained than before. we demonstrate that the texture zeros of m-nu are stable against the one-loop quantum corrections, and there exists a permutation symmetry between patterns a(1) and a(2), b-1 and b-2 or b-3 and b-4. phenomenological implications of m-nu on the neutrinoless double-beta decay and leptonic cp violation are discussed, and a realization of those texture zeros by means of the z(n) flavor symmetries is illustrated. |
