Model building by coset space dimensional reduction in ten-dimensions with direct product gauge symmetry
Toshifumi Jittoh, Masafumi Koike, Takaaki Nomura +2
We investigate ten-dimensional gauge theories whose extra six-dimensional space is a compact coset space, , and gauge group is a direct product of two Lie groups. We list up c…
Measuring Lepton Flavour Violation at LHC with Long-Lived Slepton in the Coannihilation Region
Satoru Kaneko, Joe Sato, Takashi Shimomura +2
When the mass difference between the lightest slepton, the NLSP, and the lightest neutralino, the LSP, is smaller than the tau mass, the lifetime of the lightest slepton increases…
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…
Standard(-like) Model from an SO(12) Grand Unified Theory in six-dimensions with extra-space
Takaaki Nomura, Joe Sato
We analyze a gauge-Higgs unification model which is based on a gauge theory defined on a six-dimensional spacetime with an extra-space. We impose a symmetry condition for a g…
Big-bang nucleosynthesis and the relic abundance of dark matter in a stau-neutralino coannihilation scenario
Toshifumi Jittoh, Kazunori Kohri, Masafumi Koike +3
A scenario of the Big-Bang Nucleosynthesis is analyzed within the Minimal Supersymmetric Standard Model which is consistent with a stau-neutralino coannihilation scenario to explai…
Model building by Coset space dimensional reduction scheme using ten-dimensional coset spaces
Toshifumi Jittoh, Masafumi Koike, Takaaki Nomura +2
We investigate the gauge-Higgs unification models within the scheme of the coset space dimensional reduction, beginning with a gauge theory in a fourteen-dimensional spacetime wher…
