- Freeze-in and Freeze-out in Right-Handed Neutrino Extended . . .
However, in the region of the parameter space where the freeze-in mechanism does not lead to overabundance, sterile neutrino production via the Dodelson–Widrow mechanism [19] will lead to overabundance in all simple SUSY seesaw models
- Q6 as the flavor symmetry in a non-minimal SUSY SU 5 model
Taking into account the neutrino mass problem, the SUSY SU(5)version (SUSY models in general) provides elegant mechanisms to generate massive neutrinos viaR-parity vio- lation [38,39]

citly violate lepton number and R-parity In SUSY extensions of the standard model, the R-parity of a particle is defined as R = (−1)L+3B+2S [1] and can be violated if either the baryon number (B) or lepton number (L) is not conserved, where S deno
- Unphysical Higgs Bosons and Spontaneous Violation of Lorentz . . .
12-20 Asahigaoka-cho, Hirakata 573-0026, Japan The standard theory of elementary particle physics is modified in such a way that the Higgs boson becomes unphysical and Lorentz invariance is slightly violated at the level of the S-matrix The basic technique of realizing these properties without violating the unitarity of the physical S-matrix is the use of the complex-ghost quantum field theory
