Neutrinos: How Do They Mix and Violate CP ? | | Harald Fritzsch

16 May 2000 | | Subject: | hep-ph | | Abstract: | We discuss a simple model of lepton mixing and CP violation based on the flavor democracy of charge leptons and the mass degeneracy of neutrinos. A nearly bi-maximal flavor mixing pattern, which is favored by current data on atmospheric and solar neutrino oscillations, emerges naturally from this model after explicit symmetry breaking. The rephasing-invariant strength of CP or T violation can be as large as one percent, leading to significant probability asymmetries between
u_mu o
u_e and ar{
u}_mu o ar{
u}_e (or
u_e o
u_mu) transitions in the long-baseline neutrino experiments. The possible matter effects on CP- and T-violating asymmetries are also taken into account. | | Source: | arXiv, hep-ph/0005148 | | Services: | Forum | Review | PDF | Favorites | |
