Leptonic flavour mixing influenced by flavon cross couplings (2017)
Presentation / Conference Contribution
Zhou, Y.-L. (2017, September). Leptonic flavour mixing influenced by flavon cross couplings. Presented at The XXVII International Conference on Neutrino Physics and Astrophysics (Neutrino 2016), London, EnglandWe develop an economical approach to connect flavon cross couplings with flavour mixing. A non-zero reactor mixing angle and almost maximal CP violation arise from cross couplings between flavons in the charged lepton and neutrino sectors. Within thi...
