Natural Understanding of Sterile Neutrino by Relativistic Equation
Keiichi Kimura, Akira Takamura
We derive the neutrino oscillation probabilities including sterile neutrinos by using the Dirac equation. If neutrinos have both the Dirac and the Majorana mass terms, left-handed…
Exact Oscillation Probabilities of Neutrinos in Three generations derived from Relativistic Equation
Keiichi Kimura, Akira Takamura
In three generations or more, we derive the oscillation probabilities of both Dirac and Majorana neutrinos relativistically by using the Dirac equation. We present various oscillat…
Unification of Neutrino-Neutrino and Neutrino-Antineutrino Oscillations
Keiichi Kimura, Akira Takamura
In the case of two-generation Majorana neutrinos, we derive the oscillation probabilities for , , and within a u…
New CP Phase and Exact Oscillation Probabilities of Dirac Neutrino derived from Relativistic Equation
Keiichi Kimura, Akira Takamura
We present a new formulation for deriving neutrino oscillation probabilities relativistically, based not on the Schrödinger equation but on the Dirac equation. In the context of tw…
Supernova neutrino signals by liquid Argon detector and neutrino magnetic moment
Takashi Yoshida, Akira Takamura, Keiichi Kimura +3
We study electron-neutrino and electron-antineutrino signals from a supernova with strong magnetic field detected by a 100 kton liquid Ar detector. The change of neutrino flavors b…
Neutrino-Nucleus Reaction Cross Sections for Light Element Synthesis in Supernova Explosions
T. Yoshida, T. Suzuki, S. Chiba +5
The neutrino-nucleus reaction cross sections of 4He and 12C are evaluated using new shell model Hamiltonians. Branching ratios of various decay channels are calculated to evaluate…
