Imprint of Gravitational Lensing by Population III Stars in Gamma Ray Burst Light Curves (2006)
Hirose, Y., Umemura, M., Yonehara, A., Sato, J.
We propose a novel method to extract the imprint of gravitational lensing by Pop III stars in the light curves of Gamma Ray Bursts (GRBs). Significant portions of GRBs can originate in hypernovae of...

An SU(5) SUSY Model with R-Parity Violation and Radiatively Induced Neutrino Masses (2002)
The radiatively induced neutrino mass matrix is investigated on the basis of an SU(5) SUSY model. In order to evade the proton decay, an ansatz based on a discrete symmetry $Z_2$ is assumed:...
Ambiguities of theoretical parameters and CP/T violation in neutrino factories (2001)
We study the optimal setup for observation of the CP asymmetry in neutrino factory experiments --- the baseline length, the muon energy and the analysis method. First, we point out that the...
Phenomenology of Neutrino Mass Matrix (2001)
Haba, N., Sato, J., Tanimoto, M., Yoshioka, K.
The search for possible mixing patterns of charged leptons and neutrinos is important to get clues of the origin of nearly maximal mixings, since there are some preferred bases of the lepton mass...
Possible Flavor Mixing Structures of Lepton Mass Matrices (2001)
Haba, N., Sato, J., Tanimoto, M., Yoshioka, K.
To search for possible textures of lepton mass matrices, we systematically examine flavor mixing structures which can lead to large lepton mixing angles. We find out 37 mixing patterns are consistent...
We analyze in detail lepton-flavor violation (LFV) in the charged-lepton sector such as $\mu \to e \gamma$, $\tau \to \mu \gamma$, $\mu \to eee$ and the $\mu \to e$ conversion in nuclei, within the...
Ambiguities of theoretical parameters and CP/T violation in neutrino factories (2000)
We study the sensitivity to the CP/T-violation search in the presence of ambiguities of the theoretical parameters. Three generations of neutrinos are considered. The parameters whose ambiguities are...
Matter profile effect in neutrino factory (2000)
We point out that the matter profile effect --- the effect of matter density fluctuation on the baseline --- is very important to estimate the parameters in a neutrino factory with a very long...
A Constraint on Yukawa-Coupling Unification from Lepton-Flavor Violating Processes (2000)
We present a new constraint on a lepton mixing matrix $V$ from lepton-flavor violating (LFV) processes in supersymmetric standard models with massive neutrinos. Here, we assume Yukawa-coupling...

Low-Energy Predictions of Lopsided Family Charges (2000)

CP and T violation in (long)long baseline neutrino oscillation experiments (1999)
We consider possibilities of observing CP-violation effects in neutrino oscillation experiments with low energy ($\sim$ several hundreds MeV).
The Auxiliary Mass Method beyond the Local Potential Approximation (1999)
We show that the evolution equation of the effective potential in the auxiliary mass method corresponds to a leading approximation of a certain series. This series is derived from an evolution...
End-point of the Electroweak Phase Transition using the auxiliary mass method (1999)
We study the end-point of the Electroweak phase transition using the auxiliary mass method. The end point is $m_H\sim40$ (GeV) in the case $m_t=0$ (GeV) and strongly depends on the top quark mass. A...
We investigate a phase transition of the O(N) invariant scalar model using the auxiliary mass method. We determine the critical exponent $\beta$ by calculating an effective potential below the...
Large Lepton Mixing in Seesaw Models - Coset-space Family Unification - (1998)
We show that the large mixing between $\nu_\mu$ and $\nu_\tau$ observed by the SuperKamiokande collaboration is a quite natural prediction in a large class of seesaw models. This large mixing is...
Quark and Lepton Mass Matrix in an Asymptotically Non-Free Theory (1997)

We analyze fermion mass-matrix structure in an asymptotically non-free model with 4 + 1bar generations. The texture at the GUT scale is uniquely determined by supposing that the masses of heavy...
Large Lepton Mixing in a Coset-space Family Unification on $E_7/SU(5) \times U(1)^3$ (1997)
We study a coset-space unification model for families based on $E_7/SU(5) \times U(1)^3$. We find that qualitative structure of quark and lepton mass matrices in this model describes very well the...
