Depletion of atmospheric muon-neutrino fluxes and structure of Majorana mass matrix

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We study the structures of the Dirac and Majorana mass matrices which give rise to the large lepton mixing expected from the depleted atmospheric muon-neutrino flux. In the case that the Majorana mass matrix has a hierarchy for generations, a certain kind of the neutrino Dirac mass matrix with the hierarchical structure leads to the large lepton mixing between the second generation and the third one. Our model-independent analyses serve the model-building of the mass matrices based on the quark-lepton unified theory.
