Query: Cosmological and Particle Physics Constraints on a New Non-Abelian SU(3)
  Gauge Model for Ordinary/Dark Matter Interaction   We propose a mirror model for ordinary and dark matter that assumes a new
SU(3) gauge group of transformations, as a natural extension of the Standard
Model (SM). A close study of big bang nucleosynthesis, baryon asymmetries,
cosmic microwave background bounds, galaxy dynamics, together with the Standard
Model assumptions, help us to set a limit on the mass and width of the new
gauge boson. The cross section for the elastic scattering of a dark proton by
an ordinary proton is estimated and compare to the WIMP--nucleon experimental
upper bounds. It is observed that all experimental bounds for the various cross
sections can be accommodated consistently within the gauge model. We also
suggest a way for direct detection of the new gauge boson via one example of a
SM forbidden process: $e^+ + p \rightarrow \mu^+ + X$, where $X = \Lambda$ or
$\Lambda_c$.
