Fitting high-energy Littlest Seesaw parameters using low-energy neutrino data and leptogenesis

open access: yesJournal of High Energy Physics, 2018
We show that the four high-energy Littlest Seesaw parameters in the flavour basis, namely two real Yukawa couplings plus the two right-handed neutrino masses, can be determined by an excellent fit to the seven currently constrained observables of low ...

Constraints on Exotic Mixing of Three Neutrinos [PDF]

open access: yes, 1999
Exotic explanations are considered for atmospheric neutrino observations. Our analysis includes matter effects and the mixing of all three neutrinos under the simplifying assumption of only one relevant mixing scale. Constraints from accelerator, reactor

Bimaximal Mixing in an SO(10) Minimal Higgs Model [PDF]

open access: yes, 1999
An SO(10) SUSY GUT model was previously presented based on a minimal set of Higgs fields. The quark and lepton mass matrices derived fitted the data extremely well and led to large mixing of muon- and tau-neutrinos in agreement with the atmospheric ...

Neutrino Masses and Mixing: Evidence and Implications [PDF]

open access: yes, 2002
Measurements of various features of the fluxes of atmospheric and solar neutrinos have provided evidence for neutrino oscillations and therefore for neutrino masses and mixing. We review the phenomenology of neutrino oscillations in vacuum and in matter.

Forward charm-production models and prompt neutrinos at IceCube

open access: yesJournal of High Energy Physics, 2018
We investigate the prompt neutrino background at IceCube, as determined from forward charm. We consider the role of intrinsic charm and of a recombination model and show that the contribution of these mechanisms is at most a factor two.

Constraints on mixing angles of Majorana neutrinos [PDF]

open access: yes, 1998
By combining the inputs from the neutrinoless double beta decay and the fits of cosmological models of dark matter with solar and atmospheric neutrino data, we obtain constraints on two of the mixing angles of Majorana neutrinos, which become stronger ...

The fate of hints: updated global analysis of three-flavor neutrino oscillations

open access: yesJournal of High Energy Physics, 2020
Our herein described combined analysis of the latest neutrino oscillation data presented at the Neutrino2020 conference shows that previous hints for the neutrino mass ordering have significantly decreased, and normal ordering (NO) is favored only at the

Solar mass-varying neutrino oscillations [PDF]

open access: yes, 2005
We propose that the solar neutrino deficit may be due to oscillations of mass-varying neutrinos (MaVaNs). This scenario elucidates solar neutrino data beautifully while remaining comfortably compatible with atmospheric neutrino and K2K data and with ...
