Fourier Analysis of the Parametric Resonance of the Neutrino Oscillation in the Presence of Inhomogeneous Matter
Joe Sato, Masafumi Koike, Toshihiko Ota +1
We study the parametric resonance of the neutrino oscillation through the matter whose density varies spatially. The Fourier analysis of the matter effect enables us to clarify the…
Neutrino factory optimization for non-standard interactions
Joachim Kopp, Toshihiko Ota, Walter Winter
We study the optimization of a neutrino factory with respect to non-standard neutral current neutrino interactions, and compare the results to those obtained without non-standard i…
Testing non-unitarity of neutrino mixing matrices at neutrino factories
Srubabati Goswami, Toshihiko Ota
In this paper we explore the effect of non-unitary neutrino mixing on neutrino oscillation probabilities both in vacuum and matter. In particular, we consider the chan…
Impact of non-standard neutrino interactions on future oscillation experiments
Joachim Kopp, Manfred Lindner, Toshihiko Ota +1
We study the performance of reactor and superbeam neutrino experiments in the presence of non-standard interactions (NSI). We find that for some non-standard terms, reactor and sup…
Non-standard neutrino interactions in reactor and superbeam experiments
Joachim Kopp, Manfred Lindner, Toshihiko Ota +1
The formalism of non-standard four-fermion interactions provides a convenient, model-independent way of parameterizing a wide class of ``new physics'' scenarios. In this article, w…
CP violation due to multi Froggatt-Nielsen fields
Shinya Kanemura, Koichi Matsuda, Toshihiko Ota +4
We study how to incorporate CP violation in the Froggatt--Nielsen (FN) mechanism. To this end, we introduce non-renormalizable interactions with a flavor democratic structure to th…
