| The basic task of particle physics is to explore the basic structure and basic material interactions and explore the mystery of nature. Whether neutrinos have mass, neutrino oscillation, Quark-lepton complementarity（QLC）, self-complementary（SC）, CKM and PMNS mixing matrix became the hot issue of particle physics. Daya bay neutrino experiment confirmed the phenomenon that electron antineutrinos disappeared. The phenomenon is consistent with those expectations of neutrino oscillation. On this basis, through further measurement of θ13, one can measure the parity and charge inversion. T2K experiment in Japan, RENO experiment in South Korea’s focused on θ13 measurement. Neutrinos reactor experimental data indicate the direction of theoretical study and provides experimental basis for our theory. In this paper, we reviewed neutrino mass, neutrino oscillation, the lepton PMNS mixing matrix, quark CKM mixing matrix and neutrino constant mixing matrix, nine kinds of parametric methods of the standard model. In the process of review, we noticed that Quark-lepton complementarity and self-complementary are not accurate.Meanwhilethe short baseline neutrino experiment has found signs of the existence of sterile neutrinos. As a result, we put forward a theoretical hypothesis: Quark-lepton complementarity and self-complementary are accurate, the existence of sterile neutrinos causes the deviation.According to this conjecture we take example by the extended standard model of particle physics and the "3 + 1" neutrino model. Under accurate Quark-lepton complementarity and self-complementary, we fit mixing angles and mixing matrix elements. The next section, we use a similar scheme to make tribimaximal matrix which contain highly symmetrical can be close to the experimental value. |
