Avoiding the uncertainty from correlation between |Delta m_{31}^2| and CP phase delta in nu_mu --> nu_mu long baseline experiments
Keiichi Kimura, Akira Takamura, Tadashi Yoshikawa
We introduce a new index I_{Delta m_{31}^2} to find where is the better setup of the baseline length and energy to avoid as well as possible the uncertainty from the correlation be…
Effect of Leptonic CP Phase in nu_mu --> nu_mu Oscillations
Keiichi Kimura, Akira Takamura, Tadashi Yoshikawa
In the case of large 1-3 mixing angle as sin^2(2theta13 > 0.03, we investigate the possibility for measuring the leptonic CP phase by using only nu_mu --> nu_mu oscillations indepe…
Measuring the Leptonic CP Phase in Oscillations
Keiichi Kimura, Akira Takamura, Tadashi Yoshikawa
In oscillations, we find that the effect of the CP phase becomes large in the region GeV and km. In this region, the change of the probability in t…
New Index of CP Phase Effect and Screening in Long Baseline Neutrino Experiments
Keiichi Kimura, Akira Takamura, Tadashi Yoshikawa
We introduce a new index of the leptonic CP phase dependence and derive the maximal condition for this index in a simple and general form. may…
Large Non-perturbative Effects of Small Δm^2_{21}/Δm^2_{31} and \sin θ_{13} on Neutrino Oscillation and CP Violation in Matter
Akira Takamura, Keiichi Kimura
In the framework of three generations, we consider the CP violation in neutrino oscillation with matter effects. At first, we show that the non-perturbative effects of two small pa…

Akira Takamura, Keiichi Kimura, Hidekazu Yokomakura
We study neutrino oscillation within the framework of three generations in matter. We propose a simple method to approximate the coefficients A, B and C which do not depend on the…
Overall Feature of CP dependence for Neutrino Oscillation Probability in Arbitrary Matter Profile
Hidekazu Yokomakura, Keiichi Kimura, Akira Takamura
We study the CP dependence of neutrino oscillation probability for all channels in arbitrary matter profile within three generations. We show that an oscillation probability for ν_…

K. Kimura, A. Takamura, H. Yokomakura
Within the framework of the standard three neutrino scenario, we derive an exact and simple formula of the oscillation probability in constant matter by using a ne…
Matter Enhancement of T Violation in Neutrino Oscillation
H. Yokomakura, K. Kimura, A. Takamura
We study the matter enhancement of T violation in neutrino oscillation with three generations. The magnitude of T violation is proportional to Jarlskog factor J. Recently, the eleg…
