SSP2012 - 5th International Symposium on Symmetries in Subatomic Physics

We try to envision that there might be a dark-matter world and neutrinos, especially the right-handed ones, might be coupled directly with particles in the dark-matter world. This means that the minimal Standard Model [1], which describes the ordinary-matter world to begin with, should be extended in some way. Our candidate theory would be the extended Standard Model based on $SU_c(3) \times SU_L(2) \times U(1) \times SU_f(3) \times SU_R(2)$ [2, 3], with the search of the detailed version suggested to be simplified via the two working rules, "Dirac similarity principle" and "minimum Higgs hypothesis" [4]. PACS Indices: 98.80.Bp (Origin and formation of the Universe); 12.60.-i (Models beyond the standard model); 12.10.-g (Unified field theories and models). This research is supported in part by National Science Council project (NSC 99-2112-M-002-009-MY3). We wish to thank the authors of the following books [1] for thorough reviews of the minimal Standard Model. References: [1] Ta-You Wu and W-Y.
