Baryogenesis and Asymmetric Dark Matter from The Left-Right Mirror Symmetric Model
The paper suggests a left-right mirror symmetric model to account for the
baryogenesis and asymmetric dark matter. The model can simultaneously
accommodate the standard model, neutrino physics, matter-antimatter asymmetry
and dark matter. In particular, it naturally and elegantly explains the origin
of the baryon and dark matter asymmetries, and clearly gives the close
interrelations of them. In addition, the model predicts a number of interesting
results, e.g. the cold dark matter neutrino mass is times the proton
mass. It is also feasible and promising to test the model in future
experiments.Comment: 24 pages, 4 figures. arXiv admin note: text overlap with

Neutrino Mass, Leptogenesis, and Dark Matter from The Dark Sector with
I suggest a new extension of the SM by introducing a dark sector which has
several new particles and a local symmetry. The dark particles bring
about the new and interesting physics beyond the SM. The model can generate the
tiny neutrino mass by a hybrid see-saw mechanism, achieve the leptogenesis at
the TeV scale, and account for the cold dark matter. All of the three things
collectively arise from the dark sector. In particular, it is very feasible to
test the model predictions and probe the dark sector in near future
experiments.Comment: 18 pages, 4 figures, to be published by JHEP. arXiv admin note: text
