Hybrid textures in minimal seesaw mass matrices
Srubabati Goswami, Subrata Khan, Atsushi Watanabe
In the context of minimal seesaw framework, we study the implications of Dirac and Majorana mass matrices in which two rigid properties coexist, namely, equalities among mass matri…
Lepton Flavor Model from Delta(54) Symmetry
Hajime Ishimori, Tatsuo Kobayashi, Hiroshi Okada +2
We present the lepton flavor model with , which appears typically in heterotic string models on the orbifold. Our model reproduces the tri-bimaximal mixing in the…
Leptogenesis with an almost conserved lepton number
Takehiko Asaka, Steve Blanchet
Seesaw models with a slightly broken lepton number symmetry can explain small neutrino masses, and allow for low-scale leptogenesis. We make a thorough analysis of leptogenesis wit…
Soft supersymmetry breaking terms from A4 lepton flavor symmetry
Hajime Ishimori, Tatsuo Kobayashi, Yuji Omura +1
We study the supersymmetric model with the A4 lepton flavor symmetry, in particular soft supersymmetry breaking terms, which are predicted from the A4 lepton flavor symmetry. We ev…
Drell-Yan double-spin asymmetry A_{LT} in polarized p\bar{p} collisions: Wandzura-Wilczek contribution
Yuji Koike, Kazuhiro Tanaka, Shinsuke Yoshida
The longitudinal-transverse spin asymmetry A_{LT} in the polarized Drell-Yan process depends on the twist-3 spin-dependent distributions of nucleon. In addition to the contribution…
Soft supersymmetry breaking terms from D4 x Z2 lepton flavor symmetry
Hajime Ishimori, Tatsuo Kobayashi, Hiroshi Ohki +3
We study the supersymmetric model with lepton flavor symmetry. We evaluate soft supersymmetry breaking terms, i.e. soft slepton masses and A-terms, which are predi…
Tri-bimaximal Mixing from Cascades
Naoyuki Haba, Ryo Takahashi, Morimitsu Tanimoto +1
We study fermion mass matrices of the cascade form which are compatible with the tri-bimaximal lepton mixing and generation mass hierarchy. The flat-cascade lepton matrices imply a…
Inter-Quark Potentials in Baryons and Multi-Quark Systems in QCD
H. Suganuma, A. Yamamoto, N. Sakumichi +3
We perform the first studies of various inter-quark potentials in SU(3) lattice QCD. From the accurate lattice calculation for more than 300 different patterns of three-q…
D4 Flavor Symmetry for Neutrino Masses and Mixing
Hajime Ishimori, Tatsuo Kobayashi, Hiroshi Ohki +3
We present the flavor symmetry, which is different from the previous work by Grimus and Lavoura. Our model reduces to the standard model in the low energy and there…
Deviation from tri-bimaximal neutrino mixing in A4 flavor symmetry
Mizue Honda, Morimitsu Tanimoto
The tri-bimaximal mixing is a good approximation for the present data of neutrino mixing angles. The deviation from the tri-bimaximal mixing is discussed numerically in the framewo…
