Phys. Rev. D 62, 093001 (2000) [8 pages]CP violations in lepton number violation processes and neutrino oscillationsReceived 6 March 2000; published 14 September 2000 We examine the constraints on the Maki-Nakagawa-Sakata (MNS) lepton mixing matrix from present and future experimental data of the neutrino oscillation and lepton number violation processes. We introduce a graphical representation of the CP violation phases which appear in the lepton number violation processes such as neutrinoless double beta decay, the μ--e+ conversion, and the K decay, K-→π+μ-μ-. Using this graphical representation, we derive the constraints on the CP violation phases in the lepton sector. © 2000 The American Physical Society URL:
