The Study On Related Themes Of Neutrino Mixing Issue

Neutrino physics is an important research field,it relates to the Higgs mechanism,dark matter,supersymmetry and the other possible new physics,and its special nature itself but also for the research on it has brought many difficulties.From the beginning of the Pauli conjecture that it is there for more than 80 years ago,its mysterious veil was gradually opened.From the simple massless neutrino to left-handed neutrino oscillation is confirmed,the neutrinos from supernova observations of the sun,air,etc.,to the reactor and accelerator detector built a perfect research system was set up.The precise measurement of the neutrino quality of the three generation,the determination of the properties of neutrino particles,the existence or absence of an inert neutrino has been put on the agenda.The first part of this paper,simply introduces the study of neutrino physics history,and some of the ideas and concepts in this research need are introduced;in the second part,mainly introduced the expansion,introducing inert neutrino and 3+1 model mainly includes: the introduction of inert neutrino in the original three order mixed model and the use of self complementary complementary relationship fit the experimental values;based on the theory of four order hybrid,was also four order of constant matrix,and the analysis of symmetry matrix for four order is able to agree better with the experimental value;the third part of this thesis,the CKM matrix element between the five relations extended to PMNS matrix element,which mainly include: analysis of the symmetric relation may be implied by the mixed model,through the CP complex relationship between breaking missing angle to build more equality,with five equation simplification On the basis of this,a new constant mixed matrix and a mixed matrix of finite variables are introduced.
