The Family Collider
  Granting that the $SU_c(3) \times SU_L(2) \times U(1) \times SU_f(3)$ Standard Model is valid (or, partially valid), for the real world, we propose the $\mu^+ e^-$ collider in the $10^2\, GeV$ range as the family collider. This family collider may work efficiently in producing the family Higgs particles and detecting the effects of family gauge bosons, with the range of sub-sub-fermi's (a few $10^{-2} \, fermi$'s).
