A Phenomenological Outlook on Three-flavor Atmospheric Neutrino Oscillations
نویسندگان
چکیده
The recent observations of atmospheric ν events from the Super-Kamiokande experiment are compatible with three-flavor neutrino oscillations, occurring dominantly in the νμ ↔ ντ channel and subdominantly in the νμ ↔ νe channel. We present an updated analysis of the three-flavor mass-mixing parameters consistent with the present phenomenology, including the latest 45 kTy data sample from Super-Kamiokande. A comparison with our previous results, based on 33 kTy data, shows that the oscillation evidence is strengthened, and that the neutrino mass-mixing parameters are constrained in smaller ranges.

Status of non-standard neutrino interactions.
The phenomenon of neutrino oscillations has been established as the leading mechanism behind neutrino flavor transitions, providing solid experimental evidence that neutrinos are massive and lepton flavors are mixed. Here we review sub-leading effects in neutrino flavor transitions known as non-standard neutrino interactions (NSIs), which is currently the most explored description for effects b...
متن کاملMaximal Neutrino Mixing and Maximal CP Violation
We propose a phenomenological 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 viola...
متن کاملNeutrino Mass Matrix with Approximate Flavor Symmetry
Phenomenological implications of neutrino oscillations implied by recent experimental data on pattern of neutrino mass matrix are diss-cussed. It is shown that it is possible to have a neutrino mass matrix which shows approximate flavor symmetry; the neutrino mass differences arise from flavor violation in off-diagonal Yukawa couplings. Two modest extensions of the standard model, which can emb...

متن کاملLarge Mixing and CP Violation in Neutrino Oscillations
I introduce a simple phenomenological model of lepton flavor mixing and CP violation based on the flavor democracy of charged leptons and the mass degeneracy of neutrinos. The nearly bi-maximal mixing pattern, which can interpret current data on atmospheric and solar neutrino oscillations, emerges naturally from this model. The rephasing-invariant strength of CP or T violation amounts to about ...
